Subject: [PATCH v6 1/7] common/rc: Introduce new helpers for DAX mount options and FS_XFLAG_DAX
Date: Tue, 14 Jul 2020 17:40:03 +0800
Message-ID: <20200714094009.8654-2-yangx.jy@cn.fujitsu.com> (raw)
In-Reply-To: <20200714094009.8654-1-yangx.jy@cn.fujitsu.com>

1) _require_scratch_dax_mountopt() checks both old and new DAX mount option
2) _require_dax_iflag() checks FS_XFLAG_DAX

Signed-off-by: Xiao Yang <yangx.jy@cn.fujitsu.com>
---

V5->V6:
Simplify _require_scratch_dax_mountopt because it is enough to only check
dax/dax=always mount option.  See the following reasons:
1) we cannot detect if underlying device supports dax by mounting dax=inode
   or dax=never.
2) dax=always, dax=inode, dax=never are always introduced together.
