  "message": "kprobes: fix a memory leak in function pre_handler_kretprobe()\n\nIn function pre_handler_kretprobe(), the allocated kretprobe_instance\nobject will get leaked if the entry_handler callback returns non-zero.\nThis may cause all the preallocated kretprobe_instance objects exhausted.\n\nThis issue can be reproduced by changing\nsamples/kprobes/kretprobe_example.c to probe \"mutex_unlock\".  And the fix\nis straightforward: just put the allocated kretprobe_instance object back\nonto the free_instances list.\n\n[akpm@linux-foundation.org: use raw_spin_lock/unlock]\nSigned-off-by: Jiang Liu \u003cjiang.liu@huawei.com\u003e\nAcked-by: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nAcked-by: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: \"David S.
