From: Josh Triplett Date: Thu, 28 Sep 2006 01:04:07 +0000 (+1000) Subject: [XFS] Add lock annotations to xfs_trans_update_ail and X-Git-Tag: v2.6.19-rc1~653^2~14 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=22d91f65d57a7f1a1c5fc81f47b47b0cc54ad6f7;p=linux-2.6 [XFS] Add lock annotations to xfs_trans_update_ail and xfs_trans_delete_ail xfs_trans_update_ail and xfs_trans_delete_ail get called with the AIL lock held, and release it. Add lock annotations to these two functions so that sparse can check callers for lock pairing, and so that sparse will not complain about these functions since they intentionally use locks in this manner.
