Subject: [PATCH] vfs: Undo an overly zealous MS_RDONLY -> SB_RDONLY conversion
Date: Fri, 20 Apr 2018 13:35:02 +0100	[thread overview]
Message-ID: <152422770230.23067.14348897715991489250.stgit@warthog.procyon.org.uk> (raw)

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")
