      Revert "md: allow a partially recovered device to be hot-added to an array." · d01552a7
      NeilBrown authored
      This reverts commit 7eb41885
      
      .
      
      This commit is poorly justified, I can find not discusison in email,
      and it clearly causes a problem.
      
      If a device which is being recovered fails and is subsequently
      re-added to an array, there could easily have been changes to the
      array *before* the point where the recovery was up to.  So the
      recovery must start again from the beginning.
      
      If a spare is being recovered and fails, then when it is re-added we
      really should do a bitmap-based recovery up to the recovery-offset,
      and then a full recovery from there.  Before this reversion, we only
      did the "full recovery from there" which is not corect.  After this
      reversion with will do a full recovery from the start, which is safer
      but not ideal.
      
      It will be left to a future patch to arrange the two different styles
      of recovery.

      md/raid5: fix locking in handle_stripe_clean_event() · b8a9d66d
      Roman Gushchin authored
      After commit 566c09c5 ("raid5: relieve lock contention in get_active_stripe()")
      __find_stripe() is called under conf->hash_locks + hash.
      But handle_stripe_clean_event() calls remove_hash() under
      conf->device_lock.
      
      Under some cirscumstances the hash chain can be circuited,
      and we get an infinite loop with disabled interrupts and locked hash
      lock in __find_stripe(). This leads to hard lockup on multiple CPUs
      and following system crash.
      
      I was able to reproduce this behavior on raid6 over 6 ssd disks.
      The devices_handle_discard_safely option should be set to enable trim
      support. The following script was used:
      
      for i in `seq 1 32`; do
          dd if=/dev/zero of=large$i bs=10M count=100 &
      done
      
      neilb: original was against a 3.x kernel.  I forward-ported
        to 4.3-rc.  This verison is suitable for any kernel since
        Commit: 59fc630b

      rbd: require stable pages if message data CRCs are enabled · bae818ee
      Ronny Hegewald authored
      rbd requires stable pages, as it performs a crc of the page data before
      they are send to the OSDs.
      
      But since kernel 3.9 (patch 1d1d1a76
      
      
      "mm: only enforce stable page writes if the backing device requires
      it") it is not assumed anymore that block devices require stable pages.
      
      This patch sets the necessary flag to get stable pages back for rbd.
      
      In a ceph installation that provides multiple ext4 formatted rbd
      devices "bad crc" messages appeared regularly (ca 1 message every 1-2
      minutes on every OSD that provided the data for the rbd) in the
      OSD-logs before this patch. After this patch this messages are pretty
      much gone (only ca 1-2 / month / OSD).
