Subject: [PATCH 06/13] xfs: refactor xfs_buf_ioerror_fail_without_retry
Date: Thu, 9 Jul 2020 17:04:46 +0200 [thread overview]
Message-ID: <20200709150453.109230-7-hch@lst.de> (raw)
In-Reply-To: <20200709150453.109230-1-hch@lst.de>
xfs_buf_ioerror_fail_without_retry is a somewhat weird function in
that it has two trivial checks that decide the return value, while
the rest implements a ratelimited warning. Just lift the two checks
into the caller, and give the remainder a suitable name.
