Change prepare_uretprobe() to flush the !arch_uretprobe_is_alive()
return_instance's. This is not needed correctness-wise, but can help
to avoid the failure caused by MAX_URETPROBE_DEPTH.
Note: in this case arch_uretprobe_is_alive() can be false positive,
the stack can grow after longjmp().
Ingo,
This is the changes I asked you to pull. I added v3 tag to avoid
the confusion, but the only change is that I added the acks I got.
Currently ret-probes can't work (the application will likely crash)
if the probed function does not return, and this is even documented
in

Hi,
I thought I would send this patch as an RFC. It is something I did when
another linaro engineer was modifying acpica-tools to not require /dev/mem.
It exports the 3 tables that are not currenly exported in sysfs.
Currently I do not think there is any user of this because acpica-tools can

On some architectures /dev/mem is being removed. For debug/analysis
tools like FWTS/acpidump we therefore need to expose the ACPI root
tables in sysfs like the other tables.

Hello,
This serie adds support for more instructions to the ARM BPF JIT
namely skb netdevice type retrieval, skb payload offset retrieval, and
skb packet type retrieval.
This allows 35 tests to use the JIT instead of 29 before.
This serie depends on the "BPF JIT fixes for ARM" serie sent
