src/sys/ufs/ffs: ffs_vfsops.c ffs_wapbl.c
Log Message:
Protect test/clear fs->fs_fmod with um_lock like it is already
protected in ffs_alloc.c.
When writing to disk protect moving superblock to buffer with um_lock.
Set/clear fs->fmod while mounting, updating a mount or unmounting
is safe as these operations run exclusive, either mounting creates
a new file system or the file system is suspended. Assert suspension
for update and unmount.
