Everything you ever wanted to know about Linux 2.6 -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. - 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.  Quote the   respective commit ID in Linus' tree in your patch submission to -stable.  Procedure for submitting patches to the -stable tree:  - Send the patch, after verifying that it follows the above rules, to   stable@kernel.org. - To have the patch automatically included in the stable tree, add the   the tag     Cc: stable@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 than this can be specified in the following format in   the sign-off area:      Cc: <stable@kernel.org> # .32.x: a1f84a3: sched: Check for idle     Cc: <stable@kernel.org> # .32.x: 1b9508f: sched: Rate-limit newidle     Cc: <stable@kernel.org> # .32.x: fd21073: sched: Fix affinity logic     Cc: <stable@kernel.org> # .32.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.  Review committee:  - This is made up of a number of kernel developers who have volunteered for   this task, and a few that haven't.
