Hi again Roy,

Lets see again. Do I understand you correctly: rmap 11c fixes the problem #1 but not 11b? are all later rmaps good?
rmap 11c: - oom_kill race locking fix (Andres Salomon) - elevator improvement (Andrew Morton) - dirty buffer writeout speedup (hopefully ;)) (me) - small documentation updates (me) - page_launder() never does synchronous IO, kswapd and the processes calling it sleep on higher level (me) - deadlock fix in touch_page() (me) rmap 11b:
Lets see, not oom condition, no dirty buffers (read "only"), not documentation, page_launder (no dirty...), not deadlock. Remaining is the elevator... And that can really be it! (read ahead related too...)
and 2.4.18-pre2 (or later) does not fix it?
2.4.18-pre2: - ... - Fix elevator insertion point on failed request merge (Jens Axboe) - ... pre1:
