Subject: [PATCH] btrfs: turn btrfs_destroy_delayed_refs() into void function
Date: Tue, 9 Mar 2021 17:32:54 +0800 [thread overview]
Message-ID: <1615282374-29598-1-git-send-email-yang.lee@linux.alibaba.com> (raw)
This function always return '0' and no callers use the return value.
So make it a void function.
This eliminates the following coccicheck warning:
./fs/btrfs/disk-io.c:4522:5-8: Unneeded variable: "ret". Return "0" on
line 4530
