4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowe...@redhat.com>
[ Upstream commit a9e5b73288cf1595ac2e05cf1acd1924ceea05fa ]
In do_mount() when the MS_* flags are being converted to MNT_* flags,
MS_RDONLY got accidentally convered to SB_RDONLY.
Undo this change.
Fixes: e462ec50cb5f ("VFS: Differentiate mount flags (MS_*) from internal
superblock flags")
