From 49a2a1b83ba6fa40c41968d6a28ba16e7ed0c3f7 Mon Sep 17 00:00:00 2001 From: Anil S Keshavamurthy Date: Mon, 9 Jan 2006 20:52:43 -0800 Subject: [PATCH] kprobes: changed from using spinlock to mutex Since Kprobes runtime exception handlers is now lock free as this code path is now using RCU to walk through the list, there is no need for the register/unregister{_kprobe} to use spin_{lock/unlock}_isr{save/restore}. The serialization during registration/unregistration is now possible using just a mutex. In the above process, this patch also fixes a minor memory leak for x86_64 and powerpc.
