Subject: [PATCH] btrfs: delete unneeded assignments in btrfs_defrag_file
Date: Tue, 27 Apr 2021 09:50:21 +0800	[thread overview]
Message-ID: <1619488221-29490-1-git-send-email-tiantao6@hisilicon.com> (raw)

ret is assigned -EAGAIN at line 1455 and then reassigned defrag_count
at line 1547 after exiting the while loop, but the btrfs_defrag_file
function returns a negative number indicating that the execution failed
because it does not make sense to reassign defrag_count to ret, so
delete it.
