--- Comment #6 from Tijl Coosemans <tijl@FreeBSD.org> ---
(In reply to Konstantin Belousov from comment #5)
Even with journaling disabled the final close still takes about 5 seconds of
continuous disk activity, exactly as long as calling write(2) with 128MiB. =
 And
if I set sz to 256MiB it takes 10 seconds.  Clearing an inode and updating a
few bitmaps shouldn't take that long.
