 	src/sys/ufs/ffs: ffs_vfsops.c
 
 Log Message:
 Some changes to "fs->fs_fmod" and "fs->fs_clean":
 - clear "fs->fs_fmod" after reading the super block.
 - assert we don't write a super block when mounted read-only.
 - make sure "fs->fs_clean" is one of FS_ISCLEAN or FS_WASCLEAN.
 - print "file system not clean" on every mount.
 
 Should fix PR kern/57010: ffs: mounting unclean non-root fs read-only
 causes spurious write to superblock
