Subject: [patch] 2.4.0-test4 filemap.c
Date: Sat, 15 Jul 2000 15:35:21 -0300 (BRST) [thread overview]
Message-ID: <Pine.LNX.4.21.0007151534260.17208-100000@duckman.distro.conectiva> (raw)
Hi,
the patch below could make filemap.c better behaved.
this stuff is untested and since I don't really care
about tweaks to the old VM you shouldn't bother me
about it...
regards,
Rik
