Subject: [PATCH] Btrfs: insert_new_root: Fix lock type of the extent buffer.
Date: Thu, 15 Jan 2015 12:22:03 +0530 [thread overview]
Message-ID: <1421304723-16913-1-git-send-email-chandan@linux.vnet.ibm.com> (raw)
btrfs_alloc_tree_block() returns an extent buffer on which a blocked lock has
been taken. Hence assign the appropriate value to path->locks[level].
