From 8ae2c0f64a81a93d2c394eacee29d6ced53b54f9 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Fri, 23 Nov 2007 16:28:17 +1100 Subject: [XFS] Fix sparse warning in xlog_recover_do_efd_trans. Sparse trips over the locking order in xlog_recover_do_efd_trans() when xfs_trans_delete_ail() drops the ail lock. Because the unlock is conditional, we need to either annotate with a "fake unlock" or change the structure of the code so sparse thinks the function always unlocks. Reordering the code makes it simpler, so do that.
