  "message": "ia64: ptrace_attach_sync_user_rbs: avoid \"task-\u003esignal !\u003d NULL\" checks\n\nPreparation to make task-\u003esignal immutable, no functional changes.\n\nIt doesn\u0027t matter which pointer we check under tasklist to ensure the task\nwas not released, -\u003esignal or -\u003esighand.  But we are going to make\n-\u003esignal refcountable, change the code to use -\u003esighand.\n\nNote: this code doesn\u0027t need this check and tasklist_lock at all, it\nshould be converted to use lock_task_sighand().  And, the code under\nSIGNAL_STOP_STOPPED check looks wrong.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Fenghua Yu \u003cfenghua.yu@intel.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
