Hi Linus,
please pull nilfs2 bug-fixes from
git://git.kernel.org/pub/scm/linux/kernel/git/ryusuke/nilfs2.git for-linus
The following changes since commit 091bf7624d1c90cec9e578a18529f615213ff847 Linus Torvalds (1): Linux 2.6.30-rc5
Ryusuke Konishi (6): nilfs2: fix possible recovery failure due to block creation without writer nilfs2: fix circular locking dependency of writer mutex nilfs2: ensure to clear dirty state when deleting metadata file block nilfs2: fix possible circular locking for get information ioctls nilfs2: fix lock order reversal in nilfs_clean_segments ioctl nilfs2: check size of array structured data exchanged via ioctls

The "nilfs2: check size of array structured data exchanged via ioctls" adds missing sanity checks to ioctls. These checks are needed to prevent memory access overrun in kernel code due to incorrect argument data.
The "nilfs2: ensure to clear dirty state when deleting metadata file block" fixes user-reported GC failures.
The "nilfs2: fix possible recovery failure due to block creation without writer" fixes recovery failure on mount which can happen in a boundary condition.
The "nilfs2: fix circular locking dependency of writer mutex", "nilfs2: fix possible circular locking for get information ioctls", and "nilfs2: fix lock order reversal in nilfs_clean_segments ioctl" fix circular locking problems and lock order reversal the lockdep check has detected.
Thanks, Ryusuke Konishi
