Subject: [PATCH v4 0/1] vfs: Respect MS_RDONLY at bind mount creation

This revision implements a suggestion from Mateusz Guzik to do
`mnt->mnt.mnt_flags |= MNT_READONLY`. As he pointed out, there are no writers
against which to synchronize, so we can adjust the flag directly. This becomes
obvious when we see that set_mnt_shared() sets the MNT_SHARED flag directly.
