  "message": "[PATCH] utilization of kprobe_mutex is incorrect on x86_64\n\nThe up()/down() orders are incorrect in arch/x86_64/kprobes.c file.\nkprobe_mutext is used to protect the free kprobe instruction slot list.\narch_prepare_kprobe applies for a slot from the free list, and\narch_remove_kprobe returns a slot to the free list.  The incorrect up()/down()\norders to operate on kprobe_mutex fail to protect the free list.  If 2 threads\ntry to get/return kprobe instruction slot at the same time, the free slot list\nmight be broken, or a free slot might be applied by 2 threads.\n\nSigned-off-by: Zhang Yanmin \u003cYanmin.zhang@intel.com\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
