[Devel] [PATCH RH7 07/14] vfs: Undo an overly zealous MS_RDONLY -> SB_RDONLY conversion

[Pavel Tikhomirov]

From: David Howells <dhowells at redhat.com>

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")
