[ 39/68] kprobes: adjust "fix a memory leak in function pre_handler_kretprobe()"

[Greg KH]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Jan Beulich <JBeulich@xxxxxxxx>

3.0.21's 603b63484725a6e88e4ae5da58716efd88154b1e directly used
the upstream patch, yet kprobes locking in 3.0.x uses spin_lock...()
rather than raw_spin_lock...().
