Subject: [PATCH] btrfs: turn btrfs_destroy_all_ordered_extents() into void functions
Date: Tue, 2 Mar 2021 16:57:56 +0800 [thread overview]
Message-ID: <1614675476-79534-1-git-send-email-yang.lee@linux.alibaba.com> (raw)
These functions always return '0' and no callers use the return
value. So make it a void function.
It fixes the following warning detected by coccinelle:
./fs/btrfs/disk-io.c:4522:5-8: Unneeded variable: "ret". Return "0" on
line 4530
