Subject[PATCH v6 00/15] Some bugfixs for ubi/ubifs
Date
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"

v4->v5:
1. Add new fix for ubifs, "ubifs: ubifs_releasepage: Remove ubifs_assert(0)
to valid this process"

v5->v6:
1. Add new fix for ubi: "ubi: fastmap: Fix high cpu usage of ubi_bgt by
making sure wl_pool not empty"

Zhihao Cheng (15):
ubifs: rename_whiteout: Fix double free for whiteout_ui->data
ubifs: Fix deadlock in concurrent rename whiteout and inode writeback
ubifs: Fix wrong number of inodes locked by ui_mutex in ubifs_inode
