| |
Hello,
The patches do not depend on each other.
1/2 is the trivial fix, imo -stable material. The bug is very old it seems, but today this race (leading to unbalanced unlock) manifests itself via mysterious BUG_ON's in rcu/sync.c.
2/2 is old, I forgot to send it before. It was already reviewed by Dave and Jan, but the generic/068 test from xfstests triggered the warning. This was fixed by dbad7c993053 "xfs: stop holding ILOCK over filldir callbacks" so we can hopefully kill the early-lockdep-release kludge.
Oleg.
