| |
I can' t reproduce any kind of excessive swapout with wc /usr/bin/* or other thing (cp /dev/zero /tmp/zero) with my tree (arca-39) with 64Mbyte of ram. I had not time to try clean 2.1.130 to make comparison (I just asked to some guy out there but not report yet) but I guess the trick is done by this part of my patch :
diff -u linux/mm/vmscan.c:1.1.1.2 linux/mm/vmscan.c:1.1.1.1.2.3 --- linux/mm/vmscan.c:1.1.1.2 Fri Nov 27 11:19:11 1998 +++ linux/mm/vmscan.c Fri Nov 27 11:41:42 1998 @@ -431,7 +439,7 @@ kmem_cache_reap(gfp_mask); if (buffer_over_borrow() || pgcache_over_borrow()) - shrink_mmap(i, gfp_mask); + state = 0; switch (state) { do {
I changed this bit some month ago because it was the right thing to do according to me.
I am not using sct patch btw (I had not the time to understand it yet).
