2017-02-28dm raid: bump the target versionMike Snitzer
This version bump reflects that the reshape corruption fix (commit 92a39f6cc "dm raid: fix data corruption on reshape request") is present. Done as a separate fix because the above referenced commit is marked for stable and target version bumps in a stable@ fix are a recipe for the fix to never get backported to stable@ kernels (because of target version number conflicts). Also, move RESUME_STAY_FROZEN_FLAGS up with the reset the the _FLAGS definitions now that we don't need to worry about stable@ conflicts as a result of missing context.

2017-02-28dm raid: fix data corruption on reshape requestHeinz Mauelshagen
The lvm2 sequence to manage dm-raid constructor flags that trigger a rebuild or a reshape is defined as: 1) load table with flags (e.g. rebuild/delta_disks/data_offset) 2) clear out the flags in lvm2 metadata 3) store the lvm2 metadata, reload the table to reset the flags previously established during the initial load (1) -- in order to prevent repeatedly requesting a rebuild or a reshape on activation Currently, loading an inactive table with rebuild/reshape flags specified will cause dm-raid to rebuild/reshape on resume and thus start updating the raid metadata (about the progress). When the second table reload, to reset the flags, occurs the constructor accesses the volatile progress state kept in the raid superblocks. Because the active mapping is still processing the rebuild/reshape, that position will be stale by the time the device is resumed. In the reshape case, this causes data corruption by processing already reshaped stripes again. In the rebuild case, it does _not_ cause data corruption but instead involves superfluous rebuilds. Fix by keeping the raid set frozen during the first resume and then allow the rebuild/reshape during the second resume.

2017-02-28dm raid: fix raid "check" regression due to improper cleanup in raid_message()Mike Snitzer
While cleaning up awkward branching in raid_message() a raid set "check" regression was introduced because "check" needs both MD_RECOVERY_SYNC and MD_RECOVERY_REQUESTED flags set. Fix this regression by explicitly setting both flags for the "check" case (like is also done for the "repair" case, but redundant set_bit()s are perfectly fine because it adds clarity to what is needed in response to both messages -- in addition this isn't fast path code).

2017-02-28ALSA: seq: Fix link corruption by event error handlingTakashi Iwai
The sequencer FIFO management has a bug that may lead to a corruption (shortage) of the cell linked list. When a sequencer client faces an error at the event delivery, it tries to put back the dequeued cell. When the first queue was put back, this forgot the tail pointer tracking, and the link will be screwed up. Although there is no memory corruption, the sequencer client may stall forever at exit while flushing the pending FIFO cells in snd_seq_pool_done(), as spotted by syzkaller. This patch addresses the missing tail pointer tracking at snd_seq_fifo_cell_putback(). Also the patch makes sure to clear the cell->enxt pointer at snd_seq_fifo_event_in() for avoiding a similar mess-up of the FIFO linked list.

2017-02-28ALSA: timer: Reject user params with too small ticksTakashi Iwai
When a user sets a too small ticks with a fine-grained timer like hrtimer, the kernel tries to fire up the timer irq too frequently. This may lead to the condensed locks, eventually the kernel spinlock lockup with warnings. For avoiding such a situation, we define a lower limit of the resolution, namely 1ms. When the user passes a too small tick value that results in less than that, the kernel returns -EINVAL now.
