Subject: [PATCH] vfs: fix mounting a filesystem with i_version
Date: Sun, 08 Oct 2017 00:28:21 -0400	[thread overview]
Message-ID: <1507436901.5841.4.camel@linux.vnet.ibm.com> (raw)

The mount i_version flag is not enabled in the new sb_flags.  This patch
adds the missing SB_I_VERSION flag.

Fixes: e462ec5 "VFS: Differentiate mount flags (MS_*) from internal
       superblock flags"
