[PATCH 0/3] jbd2/ext4/ocfs2: READ_ONCE for lockless jinode reads

[Li Chen <me@linux.beauty>]

This series adds READ_ONCE() for existing lockless reads of
jbd2_inode fields in jbd2 and filesystem callbacks used by ext4 and ocfs2.

This is based on Jan's suggestion in the review of the ext4 jinode
publication race fix. [1]
