From: Srikar Dronamraju Date: Thu, 29 Jul 2010 14:13:51 +0000 (+0530) Subject: perf probe: Rename common fields/functions from kprobe to probe. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0e60836bbd392300198c5c2d918c18845428a1fe;p=openwrt%2Fstaging%2Fblogic.git perf probe: Rename common fields/functions from kprobe to probe. As a precursor for perf to support uprobes, rename fields/functions that had kprobe in their name but can be shared across perf-kprobes and perf-uprobes to probe.
