Subject: [PATCH 0/4] uprobes: Kill arch_uprobe_enable/disable_step() hooks
Date: Sun, 28 Oct 2012 18:39:00 +0100 [thread overview]
Message-ID: <20121028173900.GA14621@redhat.com> (raw)
Hello.
arch_uprobe_enable/disable_step() were only needed to not break
the pending powerpc port. They buy nothing and they are simply
wrong. Uprobes should not use ptrace helpers for the stepping.
Now that powepc port was merged we should kill them asap, before
arm port.
1/4 is minor/offtopic cleanup. powerpc changes were not tested
at all and thus need the review from Ananth.
Oleg.
