Subject[PATCH v2 0/3] fix sync to flush processor cache for ext2/4 DAX files
This patchset fixes issues that sync syscall to existing DAX ex2/4
files does not flush processor cache.

Patch 1/3 adds .bmap to ext4_dax_aops so that mount -o dax works for
the journal inode.

Patch 2/3 fixes the ext4 issue by setting i_flags before ext4_set_aops()
in ext4_iget().

Patch 3/3 fixes the ext2 issue by setting i_flags before ext2_set_aops()
in ext2_iget(), i.e. same as ext4.

- Add .bmap to ext4_dax_aops, instead of disabling dax for the journal
inode. (Jan Kara)
- Initialize i_flags early in ext4_iget(). (Jan Kara)
- Update Fixes tag and add Cc to Stable. (Dan Williams)
- Add fix to ext2.

Toshi Kani (3):
1/3 ext4, dax: add ext4_bmap to ext4_dax_aops
2/3 ext4, dax: set ext4_dax_aops for dax files
3/3 ext2, dax: set ext2_dax_aops for dax files
