The following patch fixes an issue relating to remount and argument parsing. After this fix is applied, remount becomes atomic in that it either succeeds changing the mount to the new state, or it fails and leaves it in the old state. Previously it was possible for the parsing of options to fail part way though and for the fs to be left in a state where some of the new arguments had been applied, but some had not.
