From c6fd91f0bdcd294a0ae0ba2b2a7f7456ef4b7144 Mon Sep 17 00:00:00 2001 From: bibo mao Date: Sun, 26 Mar 2006 01:38:20 -0800 Subject: [PATCH] kretprobe instance recycled by parent process When kretprobe probes the schedule() function, if the probed process exits then schedule() will never return, so some kretprobe instances will never be recycled. In this patch the parent process will recycle retprobe instances of the probed function and there will be no memory leak of kretprobe instances.
