In ocfs2_remove_btree_range, when calling ocfs2_lock_refcount_tree and ocfs2_prepare_refcount_change_for_del failed, it goes to out and then tries to call mutex_unlock without mutex_lock before. And when calling ocfs2_reserve_blocks_for_rec_trunc failed, it should free ref_tree before return.

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

Hi all, Change from v1 to v2: bug fix and metadata/credits reservation improvement. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

Hi all, So I have finally finished the v3 of reflink for ocfs2. The biggest change is that we support 64bit cluster offset now(Thank Mark and Joel for it).

The kernel patch series just sent (Subject: "Btrfs: scrub: print path to corrupted files and trigger nodatasum fixup") introduces two new ioctls to do in-kernel filesystem path construction. This series provides the corresponding userspace changes, adding two new commands to the btrfs utility: -- btrfs resolve inode [-v] <inode> <path> resolves an <inode> to all
