Subject: Btrfs: add more error checking to btrfs_dirty_inode
X-Git-Tag: v2.6.35-rc3~3^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9aeead73782c4b8e2a91def36dbf95db28605c95;p=profile%2Fcommon%2Fkernel-common.git

Btrfs: add more error checking to btrfs_dirty_inode

The ENOSPC code will now return ENOSPC to btrfs_start_transaction.
btrfs_dirty_inode needs to check for this and error out appropriately.
