| Subject: vfs: Undo an overly zealous MS_RDONLY -> SB_RDONLY conversion |
| |
| From: David Howells <dhowells@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") |
