Merge branch 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2

* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2: (56 commits)
  [PATCH] fs/ocfs2/dlm/: cleanups
  ocfs2: fix compiler warnings in dlm_convert_lock_handler()
  ocfs2: dlm_print_one_mle() needs to be defined
  ocfs2: remove whitespace in dlmunlock.c
  ocfs2: move dlm work to a private work queue
  ocfs2: fix incorrect error returns
  ocfs2: tune down some noisy messages during dlm recovery
  ocfs2: display message before waiting for recovery to complete
  ocfs2: mlog in dlm_convert_lock_handler() should be ML_ERROR
  ocfs2: retry operations when a lock is marked in recovery
  ocfs2: use cond_resched() in dlm_thread()
  ocfs2: use GFP_NOFS in some dlm operations
  ocfs2: wait for recovery when starting lock mastery
  ocfs2: continue recovery when a dead node is encountered
  ocfs2: remove unneccesary spin_unlock() in dlm_remaster_locks()
  ocfs2: dlm_remaster_locks() should never exit without completing
  ocfs2: special case recovery lock in dlmlock_remote()
  ocfs2: pending mastery asserts and migrations should block each other
  ocfs2: temporarily disable automatic lock migration
  ocfs2: do not unconditionally purge the lockres in dlmlock_remote()
