docs: ABI: cleanup several ABI documentsThere are some ABI documents that, while they don't generateany warnings, they have issues when parsed by get_abi.pl scripton its output result.Address them, in order to provide a clean output.Reviewed-by: Tom Rix # for fpga-managerReviewed-By: Kajol Jain # for sysfs-bus-event_source-devices-hv_gpci and sysfs-bus-event_source-devices-hv_24x7Acked-by: Jonathan Cameron #for IIOAcked-by: Oded Gabbay # for HabanalabsAcked-by: Vaibhav Jain # for sysfs-bus-papr-pmemAcked-by: Cezary Rojewski # for catptAcked-by: Suzuki K Poulose Acked-by: Ilya Dryomov # for rbdAcked-by: Jonathan Corbet Signed-off-by: Mauro Carvalho Chehab Link: https://lore.kernel.org/r/5bc78e5b68ed1e9e39135173857cb2e753be868f.1604042072.git.mchehab+huawei@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-profiling

doc: Update the name of profiling based on sysfsThe ./kernel/ksysfs.c defines 'profiling' w/o 'profile' like"KERNEL_ATTR_RW(profiling)".

22b8ce94 - profiling: dynamically enable readprofile at runtime

Thu, 16 Oct 2008 05:01:46 +0000

profiling: dynamically enable readprofile at runtimeWay too often, I have a machine that exhibits some kind of crappybehavior. The CPU looks wedged in the kernel or it is spending way toomuch system time and I wonder what is responsible.I try to run readprofile. But, of course, Ubuntu doesn't enable it bydefault. Dang!The reason we boot-time enable it is that it takes a big bufffer that wegenerally can only bootmem alloc. But, does it hurt to at least try andruntime-alloc it?To use:echo 2 > /sys/kernel/profileThen run readprofile like normal.This should fix the compile issue with allmodconfig. I've compile-testedon 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 List of files: /linux-6.15/Documentation/ABI/testing/sysfs-profiling
