Subject: [PATCH 02/10] generic: test reflink and copy_file_range behavior with O_SYNC and FS_XFLAG_SYNC files
Date: Mon, 08 Mar 2021 20:40:14 -0800 [thread overview]
Message-ID: <161526481473.1214319.4844099354726360669.stgit@magnolia> (raw)
In-Reply-To: <161526480371.1214319.3263690953532787783.stgit@magnolia>
From: Darrick J. Wong <djwong@kernel.org>
Add two regression tests to make sure that FICLONERANGE and the splice
based copy_file_range actually flush all data and metadata to disk
before the call ends.
