Subject: [PATCH v4 00/13] Some bugfixs for ubi/ubifs

v1->v2:
  1. Add new fix for ubifs, "ubifs: Fix to add refcount once page is set
  private"
  2. Update "ubifs: Rename whiteout atomically":
     1) Move inode mode in create_whiteout()
     2) Don't check O_SYNC for whiteout, because it inherits from the old_dir
     3) Remove useless 'synced_i_size ' assignment for whiteout, because
	it's always be zero.
     4) Remove unused variable 'ui' in create_whiteout()
  3. Update "ubifs: setflags: Make dirtied_ino_d 8 bytes aligned":
     1) Align dirtied_ino_d with 8 bytes.

v2->v3:
  1. Update "ubifs: Rename whiteout atomically":
     1) Fix misspelling 'have already check the old dir inode' ->
        'have already checked the old dir inode'
     2) Fix misspelling "Whiteout don't have non-zero size" ->
        "Whiteout  have non-zero size"
  2. Update "ubifs: Fix to add refcount once page is set private"
     1) Fix commit message to explain the root cause.
  3. Update "ubi: fastmap: Add all fastmap pebs into 'ai->fastmap' when
     fm->used_blocks>=2"
     1) Add fastmap used pebs into 'ai' in for-loop, rather than in
        two-steps(Add pebs [pnum<UBI_FM_MAX_START] then add pebs
	[pnum>=UBI_FM_MAX_START] into 'ai').

v3->v4:
  1. Update "ubifs: Add missing iput if do_tmpfile() failed in rename whiteout":
     1) Move whiteout cleanup into do_tmpfile() according to Sascha's advice
  2. Add new fix for ubifs, "ubifs: ubifs_writepage: Mark page dirty after
     writing inode failed"

Zhihao Cheng (13):
  ubifs: rename_whiteout: Fix double free for whiteout_ui->data

  ubifs: setflags: Make dirtied_ino_d 8 bytes aligned

    fm->used_blocks>=2
  ubifs: ubifs_writepage: Mark page dirty after writing inode failed
