commit 03891f9c853d5c4473224478a1e03ea00d70ff8d
Merge: 47c62e4 385277b

    Merge tag 'dm-4.5-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
    
    Pull device mapper updates from Mike Snitzer:
    
     - The most significant set of changes this cycle is the Forward Error
       Correction (FEC) support that has been added to the DM verity target.
    
       Google uses DM verity on all Android devices and it is believed that
       this FEC support will enable DM verity to recover from storage
       failures seen since DM verity was first deployed as part of Android.
    
     - A stable fix for a race in the destruction of DM thin pool's
       workqueue
    
     - A stable fix for hung IO if a DM snapshot copy hit an error
    
     - A few small cleanups in DM core and DM persistent data.
    
     - A couple DM thinp range discard improvements (address atomicity of
       finding a range and the efficiency of discarding a partially mapped
       thin device)
    
     - Add ability to debug DM bufio leaks by recording stack trace when a
       buffer is allocated.  Upon detected leak the recorded stack is
       dumped.
