Subject: [PATCH 2/4] btrfs/220: discard=sync support older kernel
Date: Fri, 13 Aug 2021 09:59:33 +0800	[thread overview]
Message-ID: <7f0731e5ed53fdd5b51ff1f2e51492415a46732a.1628818510.git.anand.jain@oracle.com> (raw)
In-Reply-To: <cover.1628818510.git.anand.jain@oracle.com>

mount option -o discard=sync isn't supported on the older kernel, make
this test case older kernel compatible by checking if the mount option
is supported.
