Subject: [GIT PULL] Ceph fixes for -rc6
Hi Linus,
Please pull the following ceph fixes from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
There are two biggish things here, unfortunately. One is a locking fix
that replaces i_lock use with a ceph-private inode spinlock. This is
necessary to work around lock ordering issues which unfortunately we
didn't notice until now (it's from the lock scalability stuff a couple of
kernels back). The diffstat is large, but it's a mechanical replacement
and has been pretty well tested. The other big one is removing rbd
rollback functionality from the kernel entirely (we found a minor bug but
it is better done from userspace anyway).
There are also a handful of other small bug fixes (missing spin_unlock,
typo), some error reporting/handling on a corrupt image, a fix for the
CRUSH mapping calculation, and a fix for a the seek() regression in 3.1.
There will probably be one more lock ordering patch coming shortly, but I
want to do some more testing first.
Thanks!
sage
