  "message": "ptrace_stop: fix the race with ptrace detach+attach\n\nIf the tracer went away (may_ptrace_stop() failed), ptrace_stop() drops\ntasklist and then changes the -\u003estate from TASK_TRACED to TASK_RUNNING.\n\nThis can fool another tracer which attaches to us in between.  Change the\n-\u003estate under tasklist_lock to ensure that ptrace_check_attach() can\u0027t wrongly\nsucceed.  Also, remove the unnecessary mb().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
