      Pull SCSI fixes from James Bottomley:
       "Two straightforward fixes.
      
        One is a concurrency issue only affecting SAS connected SATA drives,
        but which could hang the storage subsystem if it triggers (because the
        outstanding command count on error never goes back to zero) and the
        other is a NO_TAG fallout from the switch to hostwide tags which
        causes the system to crash on module insertion (we've checked
        carefully and only the 53c700 family of drivers is vulnerable to this
        issue)"

      Pull btrfs fixes from Chris Mason:
       "I have a two part pull this time because one of the patches Dave
        Sterba collected needed to be against v4.7-rc2 or higher (we used
        rc4).  I try to make my for-linus-xx branch testable on top of the
        last major so we can hand fixes to people on the list more easily, so
        I've split this pull in two.
      
        This first part has some fixes and two performance improvements that
        we've been testing for some time.
      
        Josef's two performance fixes are most notable.  The transid tracking
        patch makes a big improvement on pretty much every workload"

      Btrfs: fix ->iterate_shared() by upgrading i_rwsem for delayed nodes · 02dbfc99
      Omar Sandoval authored
      Commit fe742fd4 ("Revert "btrfs: switch to ->iterate_shared()"")
      backed out the conversion to ->iterate_shared() for Btrfs because the
      delayed inode handling in btrfs_real_readdir() is racy. However, we can
      still do readdir in parallel if there are no delayed nodes.
      
      This is a temporary fix which upgrades the shared inode lock to an
      exclusive lock only when we have delayed items until we come up with a
      more complete solution. While we're here, rename the
      btrfs_{get,put}_delayed_items functions to make it very clear that
      they're just for readdir.
      
      Tested with xfstests and by doing a parallel kernel build:
      
      	while make tinyconfig && make -j4 && git clean dqfx; do
      		:
      	done
      
      along with a bunch of parallel finds in another shell:
      
      	while true; do
      		for ((i=0; i<4; i++)); do
      			find . >/dev/null &
      		done
      		wait
      	done
