Subject[PATCH 0/5] reiserfs lock inversion fixes on xattr
Date
Hi,

Christian Kujau's use of dbench to test reiserfs xattr has inspired me.
I tried dbench -x yesterday and got various soft-lockups and lockdep
reports.

I fixed all those I've seen in this batch and it passed through 6 hours
of stress testing (if a loop of dbench -x -t 60 20 can be called stress
testing) and things look pretty fine now.

I hope you can give it a try (and/or review) before I send the whole
to Linus.

Thanks!

It's on:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
reiserfs/kill-bkl

How to get it:

git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
cd linux-2.6.git
git-pull git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git reiserfs/kill-bkl
