Linus, The following patch changes swap_writepage() to try to do write clustering of phisically contiguous pages which are dirty and in the swapcache. Do you want to include it in 2.4 ? diff -Nur --exclude-from=exclude linux.orig/include/linux/mm.h linux/include/linux/mm.h ---

[PATCH] e820 memory detection fix for ThinkPad

Hi Linus, Alan, lkml-readers, I first sent this two weeks ago, but other than a suggestion from a linux-kernel reader, I got no response. This small patch didn't appear in a 2.4.0-test kernel either, so I'm just submitting it again. This is a tiny patch to make the int15/e820 memory

I am fairly confident something in ac2 is fishy. I can repeatable get ac2 to fail with PCMCIA and also reiserfs under load, I absolutely cannot get these failures without ac2. The PCMCIA thing is unlikely to be related (there are no changes on any PCMCIA that actually worked on 13pre4).
