Subject: [PATCH 01/24] vfs: Undo an overly zealous MS_RDONLY -> SB_RDONLY conversion [ver #7]
Date: Thu, 19 Apr 2018 14:31:08 +0100 [thread overview]
Message-ID: <152414466871.23902.14667248706795552315.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <152414466005.23902.12967974041384198114.stgit@warthog.procyon.org.uk>
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")
