Hi gang, Here''s some trivial cleanups that I''ve built up while reading through the code. They''ve been run through xfstests -g quick. - z -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Implemented the suggestions. Also, moved the ocfs2_orphan_scan_init() to the end of ocfs2_fill_super() instead of calling it earlier in ocfs2_initialize_super(). Sunil

Patch 5 has been respun with the recommended change... remove the ex argument in ocfs2_orphan_scan_lock() and ocfs2_orphan_scan_unlock(). Sunil

This patch adds jbd_lock_bh_state() and jbd_unlock_bh_state() around accessses to jh->b_committed_data.

Next two patches are backport of orphan scan timer patches to ocfs2-1.4

All, Please review the patches backported to 1.4 from mainline. Sunil

Hi Linus, My for-linus branch has a one line fix: git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus Sage hit a deadlock with ceph on btrfs, and Josef tracked it down to a regression in our initial rc1 pull. When doing nocow writes we were sometimes starting a transaction with locks held. Josef Bacik (1) commits (+1/-0): Btrfs: release path before starting

Hello, the following patch series implements quotas for OCFS2. The patch series is based on: git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git linux-next I've adressed Joel's comments, also node recovery is now fully working and I've fixed a few issues I found during my testing. So I'm currently not aware of any bugs. Please review, test, comment. Thanks.

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
