From 63c3d556fb1d9f4d51f0c135341f873557ab848b Mon Sep 17 00:00:00 2001

Subject: (diskfs_set_hypermetadata): If CLEAN is not set, make sure we clear
 the clean bit on disk.  Always call sync_disk (with appropriate WAIT).
 (diskfs_readonly_changed): Don't do set_hypermetadata here. (copy_sblock):
 Don't track clean state here.
