+dm_bow (backup on write)
+========================
+
+dm_bow is a device mapper driver that uses the free space on a device to back up
+data that is overwritten. The changes can then be committed by a simple state
+change, or rolled back by removing the dm_bow device and running a command line
+utility over the underlying device.
+
+dm_bow has three states, set by writing ‘1’ or ‘2’ to /sys/block/dm-?/bow/state.
+It is only possible to go from state 0 (initial state) to state 1, and then from
+state 1 to state 2.
+
+State 0: dm_bow collects all trims to the device and assumes that these mark
+free space on the overlying file system that can be safely used. Typically the
+mount code would create the dm_bow device, mount the file system, call the
+FITRIM ioctl on the file system then switch to state 1. These trims are not
+propagated to the underlying device.
+
+State 1: All writes to the device cause the underlying data to be backed up to
+the free (trimmed) area as needed in such a way as they can be restored.
+However, the writes, with one exception, then happen exactly as they would
+without dm_bow, so the device is always in a good final state. The exception is
+that sector 0 is used to keep a log of the latest changes, both to indicate that
+we are in this state and to allow rollback. See below for all details. If there
+isn't enough free space, writes are failed with -ENOSPC.
+
+State 2: The transition to state 2 triggers replacing the special sector 0 with
+the normal sector 0, and the freeing of all state information. dm_bow then
+becomes a pass-through driver, allowing the device to continue to be used with
+minimal performance impact.
+
+Usage
+=====
+dm-bow takes one command line parameter, the name of the underlying device.
+
+dm-bow will typically be used in the following way. dm-bow will be loaded with a
+suitable underlying device and the resultant device will be mounted. A file
+system trim will be issued via the FITRIM ioctl, then the device will be
+switched to state 1. The file system will now be used as normal. At some point,
+the changes can either be committed by switching to state 2, or rolled back by
+unmounting the file system, removing the dm-bow device and running the command
+line utility. Note that rebooting the device will be equivalent to unmounting
+and removing, but the command line utility must still be run
+
+Details of operation in state 1
+===============================
+
+dm_bow maintains a type for all sectors. A sector can be any of:
+
+SECTOR0
+SECTOR0_CURRENT
+UNCHANGED
+FREE
+CHANGED
+BACKUP
+
+SECTOR0 is the first sector on the device, and is used to hold the log of
+changes. This is the one exception.
+
+SECTOR0_CURRENT is a sector picked from the FREE sectors, and is where reads and
+writes from the true sector zero are redirected to. Note that like any backup
+sector, if the sector is written to directly, it must be moved again.
+
+UNCHANGED means that the sector has not been changed since we entered state 1.
+Thus if it is written to or trimmed, the contents must first be backed up.
+
+FREE means that the sector was trimmed in state 0 and has not yet been written
+to or used for backup. On being written to, a FREE sector is changed to CHANGED.
+
+CHANGED means that the sector has been modified, and can be further modified
+without further backup.
+
+BACKUP means that this is a free sector being used as a backup. On being written
+to, the contents must first be backed up again.
+
+All backup operations are logged to the first sector. The log sector has the
+format:
+--------------------------------------------------------
+| Magic | Count | Sequence | Log entry | Log entry | …
+--------------------------------------------------------
+
+Magic is a magic number. Count is the number of log entries. Sequence is 0
+initially. A log entry is
+
+-----------------------------------
+| Source | Dest | Size | Checksum |
+-----------------------------------
+
+When SECTOR0 is full, the log sector is backed up and another empty log sector
+created with sequence number one higher. The first entry in any log entry with
+sequence > 0 therefore must be the log of the backing up of the previous log
+sector. Note that sequence is not strictly needed, but is a useful sanity check
+and potentially limits the time spent trying to restore a corrupted snapshot.
+
+On entering state 1, dm_bow has a list of free sectors. All other sectors are
+unchanged. Sector0_current is selected from the free sectors and the contents of
+sector 0 are copied there. The sector 0 is backed up, which triggers the first
+log entry to be written.

+a directory entry is spotty as a result of the cache mechanism not
+retesting the credentials because of the assumption, a privileged
+caller can fill cache, then a lower privilege can read the directory
+cache.  The uneven security model where cache, upperdir and workdir
+are opened at privilege, but accessed without creating a form of

+# How do I submit patches to Android Common Kernels
+
+1. BEST: Make all of your changes to upstream Linux. If appropriate, backport to the stable releases.
+   These patches will be merged automatically in the corresponding common kernels. If the patch is already
+   in upstream Linux, post a backport of the patch that conforms to the patch requirements below.
+   - Do not send patches upstream that contain only symbol exports. To be considered for upstream Linux,
+additions of `EXPORT_SYMBOL_GPL()` require an in-tree modular driver that uses the symbol -- so include
+the new driver or changes to an existing driver in the same patchset as the export.
+   - When sending patches upstream, the commit message must contain a clear case for why the patch
+is needed and beneficial to the community. Enabling out-of-tree drivers or functionality is not
+not a persuasive case.
+
+2. LESS GOOD: Develop your patches out-of-tree (from an upstream Linux point-of-view). Unless these are
+   fixing an Android-specific bug, these are very unlikely to be accepted unless they have been
+   coordinated with kernel-team@android.com. If you want to proceed, post a patch that conforms to the
+   patch requirements below.
+
+# Common Kernel patch requirements
+
+- All patches must conform to the Linux kernel coding standards and pass `script/checkpatch.pl`
+- Patches shall not break gki_defconfig or allmodconfig builds for arm, arm64, x86, x86_64 architectures
+(see  https://source.android.com/setup/build/building-kernels)
+- If the patch is not merged from an upstream branch, the subject must be tagged with the type of patch:
+`UPSTREAM:`, `BACKPORT:`, `FROMGIT:`, `FROMLIST:`, or `ANDROID:`.
+- All patches must have a `Change-Id:` tag (see https://gerrit-review.googlesource.com/Documentation/user-changeid.html)
+- If an Android bug has been assigned, there must be a `Bug:` tag.
+- All patches must have a `Signed-off-by:` tag by the author and the submitter
+
+Additional requirements are listed below based on patch type
+
+## Requirements for backports from mainline Linux: `UPSTREAM:`, `BACKPORT:`
+
+- If the patch is a cherry-pick from Linux mainline with no changes at all
+    - tag the patch subject with `UPSTREAM:`.
+    - add upstream commit information with a `(cherry picked from commit ...)` line
+    - Example:
+        - if the upstream commit message is
+```
+        important patch from upstream
+
+        This is the detailed description of the important patch
+
+        Signed-off-by: Fred Jones <fred.jones@foo.org>
+```
+>- then Joe Smith would upload the patch for the common kernel as
+```
+        UPSTREAM: important patch from upstream
+
+        This is the detailed description of the important patch
+
+        Signed-off-by: Fred Jones <fred.jones@foo.org>
+
+        Bug: 135791357
+        Change-Id: I4caaaa566ea080fa148c5e768bb1a0b6f7201c01
+        (cherry picked from commit c31e73121f4c1ec41143423ac6ce3ce6dafdcec1)
+        Signed-off-by: Joe Smith <joe.smith@foo.org>
+```
+
+- If the patch requires any changes from the upstream version, tag the patch with `BACKPORT:`
+instead of `UPSTREAM:`.
+    - use the same tags as `UPSTREAM:`
+    - add comments about the changes under the `(cherry picked from commit ...)` line
+    - Example:
+```
+        BACKPORT: important patch from upstream
+
+        This is the detailed description of the important patch
+
+        Signed-off-by: Fred Jones <fred.jones@foo.org>

+        Change-Id: I4caaaa566ea080fa148c5e768bb1a0b6f7201c01
+        (cherry picked from commit c31e73121f4c1ec41143423ac6ce3ce6dafdcec1)
+        [joe: Resolved minor conflict in drivers/foo/bar.c ]
+        Signed-off-by: Joe Smith <joe.smith@foo.org>
+```
+
+## Requirements for other backports: `FROMGIT:`, `FROMLIST:`,
+
+- If the patch has been merged into an upstream maintainer tree, but has not yet
+been merged into Linux mainline
+    - tag the patch subject with `FROMGIT:`
+    - add info on where the patch came from as `(cherry picked from commit <sha1> <repo> <branch>)`. This
+must be a stable maintainer branch (not rebased, so don't use `linux-next` for example).
+    - if changes were required, use `BACKPORT: FROMGIT:`
+    - Example:
+        - if the commit message in the maintainer tree is
+```
+        important patch from upstream
+
+        This is the detailed description of the important patch
+
+        Signed-off-by: Fred Jones <fred.jones@foo.org>

+>- then Joe Smith would upload the patch for the common kernel as

+
+        This is the detailed description of the important patch
+
+        Signed-off-by: Fred Jones <fred.jones@foo.org>
+
+        Bug: 135791357
+        (cherry picked from commit 878a2fd9de10b03d11d2f622250285c7e63deace

+        Signed-off-by: Joe Smith <joe.smith@foo.org>
+```
+
+
+- If the patch has been submitted to LKML, but not accepted into any maintainer tree
+    - tag the patch subject with `FROMLIST:`
+    - add a `Link:` tag with a link to the submittal on lore.kernel.org
+    - add a `Bug:` tag with the Android bug (required for patches not accepted into
+a maintainer tree)
+    - if changes were required, use `BACKPORT: FROMLIST:`
+    - Example:
+```
+        FROMLIST: important patch from upstream
+
+        This is the detailed description of the important patch
+

+        Signed-off-by: Joe Smith <joe.smith@foo.org>
+```
+
+## Requirements for Android-specific patches: `ANDROID:`
+
+- If the patch is fixing a bug to Android-specific code
+    - tag the patch subject with `ANDROID:`
+    - add a `Fixes:` tag that cites the patch with the bug
+    - Example:
+```
+        ANDROID: fix android-specific bug in foobar.c
+
+        This is the detailed description of the important fix
+
+        Fixes: 1234abcd2468 ("foobar: add cool feature")
+        Change-Id: I4caaaa566ea080fa148c5e768bb1a0b6f7201c01
+        Signed-off-by: Joe Smith <joe.smith@foo.org>
+```
+
+- If the patch is a new feature
+    - tag the patch subject with `ANDROID:`
+    - add a `Bug:` tag with the Android bug (required for android-specific features)
