Subject: [RFC PATCH] btrfs-progs: filesystem: du: skip file that permission denied
Date: Sun, 21 Nov 2021 07:47:05 +0000 [thread overview]
Message-ID: <20211121074705.8615-1-realwakka@gmail.com> (raw)
This patch handles issue #421. Filesystem du command fails and exit
when it access file that has permission denied. But it can continue the
command except the files. This patch recovers ret value when permission
denied.
