Subject: [PATCH v24 02/11] xfs: Capture buffers for delayed ops
Date: Tue, 24 Aug 2021 15:44:25 -0700	[thread overview]
Message-ID: <20210824224434.968720-3-allison.henderson@oracle.com> (raw)
In-Reply-To: <20210824224434.968720-1-allison.henderson@oracle.com>

This patch enables delayed operations to capture held buffers with in
the xfs_defer_capture. Buffers are then rejoined to the new
transaction in xlog_finish_defer_ops

Signed-off-by: Allison Henderson <allison.henderson@oracle.com>
