Description Alexander Larsson 2003-02-25 19:17:38 UTC 
Every time I start and exit X the sum of "Active + Inact_dirty + Inact_laundry +
Inact_clean + MemFree" in /proc/meminfo drops by about 12 megs.

kernel is: 2.4.20-2.50
XFree86 is: 4.2.00.901-20030212.0

Commenting out Load "DRI" in XF86Config removes the leak.
Comment 4 Mike A. Harris 2003-02-25 19:28:57 UTC 
attach /var/log/messages too to peekaboo at agpgart loading et al.

This also happens on at least i8x0 cards.
This is not nptl related, but seems rmap related.
Arjans kernel-2.4.20-5nonptlfixrmap build fixes it. Waiting on an NPTL enabled
build to test that.
Comment 7 Bill Nottingham 2003-02-27 17:15:50 UTC 
Should be fixed in -6.
Comment 8 Jay Turner 2003-02-28 02:49:20 UTC 
Fix confirmed with the latest kernel.
Comment 9 Mike A. Harris 2003-02-28 07:50:38 UTC 
Just to clarify with a bit more detail for those who might find this bug
report when doing a bugzilla query, this problem was due to a refcount
bug in rmap with respect to PageReserved pages. DRM marks it's pages as
PageReserved and was affected by this bug. (In Arjan's words)

Problem fixed in kernel-2.4.20-6 by Arjan The Machine(TM)  ;o)
