Pull btrfs fixes from Chris Mason: "The biggest of these comes from Liu Bo, who tracked down a hang we've been hitting since moving to kernel workqueues (it's a btrfs bug, not in the generic code). His patch needs backporting to 3.16 and 3.15 stable, which I'll send once this is in. Otherwise these are assorted fixes. Most were integrated last week during KS, but I wanted to give everyone the chance to test the result, so I waited for rc2 to come out before sending" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (24 commits) Btrfs: fix task hang under heavy compressed write Btrfs: fix filemap_flush call in btrfs_file_release Btrfs: fix crash on endio of reading corrupted block btrfs: fix leak in qgroup_subtree_accounting() error path btrfs: Use right extent length when inserting overlap extent map.

stable_kernel_rules.txt
Everything you ever wanted to know about Linux -stable releases.
Rules on what kind of patches are accepted, and which ones are not, into the
"-stable" tree:
- It must be obviously correct and tested.
- It cannot be bigger than 100 lines, with context.
- It must fix only one thing.
- It must fix a real bug that bothers people (not a, "This could be a
problem..." type thing).
- It must fix a problem that causes a build error (but not for things
marked CONFIG_BROKEN), an oops, a hang, data corruption, a real
security issue, or some "oh, that's not good" issue. In short, something
critical.
- Serious issues as reported by a user of a distribution kernel may also
be considered if they fix a notable performance or interactivity issue.
As these fixes are not as obvious and have a higher risk of a subtle
regression they should only be submitted by a distribution kernel
maintainer and include an addendum linking to a bugzilla entry if it
exists and additional information on the user-visible impact.
- New device IDs and quirks are also accepted.
- No "theoretical race condition" issues, unless an explanation of how the
race can be exploited is also provided.
- It cannot contain any "trivial" fixes in it (spelling changes,
whitespace cleanups, etc).
- It must follow the Documentation/SubmittingPatches rules.
- It or an equivalent fix must already exist in Linus' tree (upstream).
Procedure for submitting patches to the -stable tree:
- If the patch covers files in net/ or drivers/net please follow netdev stable
submission guidelines as described in
Documentation/networking/netdev-FAQ.txt
- Send the patch, after verifying that it follows the above rules, to
stable@vger.kernel.org. You must note the upstream commit ID in the
changelog of your submission, as well as the kernel version you wish
it to be applied to.
- To have the patch automatically included in the stable tree, add the tag
Cc: stable@vger.kernel.org
in the sign-off area. Once the patch is merged it will be applied to
the stable tree without anything else needing to be done by the author
or subsystem maintainer.
- If the patch requires other patches as prerequisites which can be
cherry-picked, then this can be specified in the following format in
the sign-off area:
Cc: <stable@vger.kernel.org> # 3.3.x: a1f84a3: sched: Check for idle
Cc: <stable@vger.kernel.org> # 3.3.x: 1b9508f: sched: Rate-limit newidle
Cc: <stable@vger.kernel.org> # 3.3.x: fd21073: sched: Fix affinity logic
Cc: <stable@vger.kernel.org> # 3.3.x
Signed-off-by: Ingo Molnar <mingo@elte.hu>
The tag sequence has the meaning of:
git cherry-pick a1f84a3
git cherry-pick 1b9508f
git cherry-pick fd21073
git cherry-pick <this commit>
- The sender will receive an ACK when the patch has been accepted into the
queue, or a NAK if the patch is rejected. This response might take a few
days, according to the developer's schedules.
- If accepted, the patch will be added to the -stable queue, for review by
other developers and by the relevant subsystem maintainer.
- Security patches should not be sent to this alias, but instead to the
documented security@kernel.org address.
Review cycle:
- When the -stable maintainers decide for a review cycle, the patches will be
sent to the review committee, and the maintainer of the affected area of
the patch (unless the submitter is the maintainer of the area) and CC: to
the linux-kernel mailing list.
- The review committee has 48 hours in which to ACK or NAK the patch.
- If the patch is rejected by a member of the committee, or linux-kernel
members object to the patch, bringing up issues that the maintainers and
members did not realize, the patch will be dropped from the queue.
- At the end of the review cycle, the ACKed patches will be added to the
latest -stable release, and a new -stable release will happen.
- Security patches will be accepted into the -stable tree directly from the
security kernel team, and not go through the normal review cycle.
Contact the kernel security team for more details on this procedure.
Trees:
- The queues of patches, for both completed versions and in progress
versions can be found at:
http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git
- The finalized and tagged releases of all stable kernels can be found
in separate branches per version at:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git
Review committee:
- This is made up of a number of kernel developers who have volunteered for
this task, and a few that haven't.
