doc: Update the name of profiling based on sysfs

2012-12-03T10:11:51Z

The ./kernel/ksysfs.c defines 'profiling' w/o 'profile' like "KERNEL_ATTR_RW(profiling)". We need to synchronize the content between ksys.c source and kernel doc. Signed-off-by: Hyeonjun Lim Signed-off-by: Jiri Kosina

profiling: dynamically enable readprofile at runtime

Way too often, I have a machine that exhibits some kind of crappy behavior. The CPU looks wedged in the kernel or it is spending way too much system time and I wonder what is responsible. I try to run readprofile. But, of course, Ubuntu doesn't enable it by default. Dang! The reason we boot-time enable it is that it takes a big bufffer that we generally can only bootmem alloc. But, does it hurt to at least try and runtime-alloc it? To use: echo 2 > /sys/kernel/profile Then run readprofile like normal. This should fix the compile issue with allmodconfig. I've compile-tested on a bunch more configs now including a few more architectures. Signed-off-by: Dave Hansen Acked-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
