      dm snapshot: add new persistent store option to support overflow · b0d3cc01
      Mike Snitzer authored
      Commit 76c44f6d introduced the possibly for "Overflow" to be reported
      by the snapshot device's status.  Older userspace (e.g. lvm2) does not
      handle the "Overflow" status response.
      
      Fix this incompatibility by requiring newer userspace code, that can
      cope with "Overflow", request the persistent store with overflow support
      by using "PO" (Persistent with Overflow) for the snapshot store type.

      genirq: Export handle_bad_irq · 9d67dc5d
      Arnd Bergmann authored
      A cleanup of the omap gpio driver introduced a use of the
      handle_bad_irq() function in a device driver that can be
      a loadable module.
      
      This broke the ARM allmodconfig build:
      
      ERROR: "handle_bad_irq" [drivers/gpio/gpio-omap.ko] undefined!
      
      This patch exports the handle_bad_irq symbol in order to
      allow the use in modules.

      dm cache: fix NULL pointer when switching from cleaner policy · 2bffa150
      Joe Thornber authored
      The cleaner policy doesn't make use of the per cache block hint space in
      the metadata (unlike the other policies).  When switching from the
      cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
      was observed.  The crash was caused by bugs in dm-cache-metadata.c
      when trying to skip creation of the hint btree.
      
      The minimal fix is to change hint size for the cleaner policy to 4 bytes
      (only hint size supported).

      drm: Fix locking for sysfs dpms file · 621bd0f6
      Daniel Vetter authored
      With atomic drivers we need to make sure that (at least in general)
      property reads hold the right locks. But the legacy dpms property is
      special and can be read locklessly. Since userspace loves to just
      randomly look at that all the time (like with "status") do that.
      
      To make it clear that we play tricks use the READ_ONCE compiler
      barrier (and also for paranoia).
      
      Note that there's not really anything bad going on since even with the
      new atomic paths we eventually end up not chasing any pointers (and
      hence possibly freed memory and other fun stuff). The locking WARNING
      has been added in
      
      commit 88a48e29

          drm: add atomic properties
      
      but since drivers are converting not everyone will have seen this from

      mode_config.connection_mutex, but we can do a bit better.

      crash in md-raid1 and md-raid10 due to incorrect list manipulation · a452744b
      Mikulas Patocka authored
      The commit 55ce74d4 (md/raid1: ensure
      device failure recorded before write request returns) is causing crash in
      the LVM2 testsuite test shell/lvchange-raid.sh. For me the crash is 100%
      reproducible.
      
      The reason for the crash is that the newly added code in raid1d moves the
      list from conf->bio_end_io_list to tmp, then tests if tmp is non-empty and
      then incorrectly pops the bio from conf->bio_end_io_list (which is empty
      because the list was alrady moved).
      
      Raid-10 has a similar bug.
