I run a 2.4.17 system with high filesystem load and experience the following problem: after running some hours with ext2 I got a lot of these messages:

addr: Specifies the address of the variable. old_val_addr: Specifies the address of the old value to be checked against (and conditionally updated with) the value of the variable.

Hum think I'm going to test this idea out tonight, quick question without swap at what point would the kernel stop giving memory up for cache

This patch adds a swap kernel commandline option, so that you can add a swap partition before init starts running on a low-memory machine. The patch is against 2.4.0-test11-pre7 ...
