Looks fine to me. I am going to add this to
git://git.kernel.org/pub/scm/linux/kernel/git/oleg/misc uprobes/core
Ananth. "4/9 uretprobes/ppc" looks "obviously correct", but could you
please review and ack/nack ?
To remind, this series depends on other changes in uprobes core
and kernel/trace/trace_uprobe.c, please see the full stat below.
I'll wait for the comments a bit, after that I'll ask Ingo to
pull if nobody objects.
Anton Arapov (9):
uretprobes: Introduce uprobe_consumer->ret_handler()
uretprobes: Reserve the first slot in xol_vma for trampoline
uretprobes/x86: Hijack return address
uretprobes/ppc: Hijack return address
uretprobes: Return probe entry, prepare_uretprobe()
uretprobes: Return probe exit, invoke handlers
