Inact_clean + MemFree" in /proc/meminfo drops by about 12 megs.

Commenting out Load "DRI" in XF86Config removes the leak.

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)
