Subject: [PATCH 1/3] uprobes/x86: Rename *riprel* helpers to make the naming consistent
Date: Sun, 27 Apr 2014 18:52:23 +0200 [thread overview]
Message-ID: <20140427165223.GA4013@redhat.com> (raw)
In-Reply-To: <20140427165200.GA3956@redhat.com>
handle_riprel_insn(), pre_xol_rip_insn() and handle_riprel_post_xol()
look confusing and inconsistent. Rename them into riprel_analyze(),
riprel_pre_xol(), and riprel_post_xol() respectively.
No changes in compiled code.
