Subject: [PATCH 05/11] xfs: pass flags and return gc errors from xfs_blockgc_free_quota
Date: Sat, 23 Jan 2021 10:52:27 -0800 [thread overview]
Message-ID: <161142794741.2171939.10175775024910240954.stgit@magnolia> (raw)
In-Reply-To: <161142791950.2171939.3320927557987463636.stgit@magnolia>
From: Darrick J. Wong <djwong@kernel.org>
Change the signature of xfs_blockgc_free_quota in preparation for the
next few patches. Callers can now pass EOF_FLAGS into the function to
control scan parameters; and the function will now pass back any
corruption errors seen while scanning, though for our retry loops we'll
just try again unconditionally.
