Next time, please don't forget to mention the mainline commit IDs in
addition to the message subjects, it helps a lot. The IDs from the
stable branches are less important since it's generally quite easy
to find them thanks to the mainline ID which appears in the message.
Just for reference :
- ca5358e ("deal with deadlock in d_walk()")
- 2159184 ("d_walk() might skip too much")
Thanks,
Willy
