[PATCH] Fix warnings for WARN_ON if CONFIG_BUG is disabled

2006-10-20T17:26:38Z

In most cases the return value of WARN_ON() is ignored. If the generic definition for the !CONFIG_BUG case is used this will result in a warning: CC kernel/sched.o In file included from include/linux/bio.h:25, from include/linux/blkdev.h:14, from kernel/sched.c:39: include/linux/ioprio.h: In function âtask_ioprioâ: include/linux/ioprio.h:50: warning: statement with no effect kernel/sched.c: In function âcontext_switchâ: kernel/sched.c:1834: warning: statement with no effect Signed-off-by: Ralf Baechle Cc: Jeremy Fitzhardinge Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Fix WARN_ON / WARN_ON_ONCE regression

2006-10-06T15:53:39Z

Tim and Ananiev report that the recent WARN_ON_ONCE changes cause increased cache misses with the tbench workload. Apparently due to the access to the newly-added static variable. Rearrange the code so that we don't touch that variable unless the warning is going to trigger. Also rework the logic so that the static variable starts out at zero, so we can move it into bss. It would seem logical to mark the static variable as __read_mostly too. But it would be wrong, because that would put it back into the vmlinux image, and the kernel will never read from this variable in normal operation anyway. Unless the compiler or hardware go and do some prefetching on us? For some reason this patch shrinks softirq.o text by 40 bytes.

[PATCH] Let WARN_ON/WARN_ON_ONCE return the condition

2006-09-29T16:18:06Z

Letting WARN_ON/WARN_ON_ONCE return the condition means that you could do if (WARN_ON(blah)) { handle_impossible_case } Rather than if (unlikely(blah)) { WARN_ON(1) handle_impossible_case } I checked all the newly added WARN_ON_ONCE users and none of them test the return status so we can still change it.

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
