From: Josh Triplett Date: Wed, 27 Sep 2006 08:49:26 +0000 (-0700) Subject: [PATCH] jbd: add lock annotation to jbd_sync_bh X-Git-Tag: v2.6.19-rc1~1001 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e7ab8d65055e9b9dfc131d0467cfc5a8368d7ee4;p=linux-2.6 [PATCH] jbd: add lock annotation to jbd_sync_bh jbd_sync_bh releases journal->j_list_lock. Add a lock annotation to this function so that sparse can check callers for lock pairing, and so that sparse will not complain about this function since it intentionally uses the lock in this manner.
