From 13859c984301ac4c1b2b3504b9f342aaddaa4a8a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 12 Mar 2020 16:52:51 -0700 Subject: xfs: cleanup xfs_log_unmount_write Move the code for verifying the iclog state on a clean unmount into a helper, and instead of checking the iclog state just rely on the shutdown check as they are equivalent. Also remove the ifdef DEBUG as the compiler is smart enough to eliminate the dead code for non-debug builds. Signed-off-by: Christoph Hellwig Reviewed-by: Brian Foster Reviewed-by: Darrick J.
