Date: Sun, 25 Oct 2015 16:26:37 +0100 From: Oleg Nesterov <oleg@...hat.com> To: Andrew Morton <akpm@...ux-foundation.org>, Markus Pargmann <mpa@...gutronix.de> Cc: nbd-general@...ts.sourceforge.net, linux-kernel@...r.kernel.org Subject: [PATCH -mm 1/3] nbd: nbd_thread_send: remove the unnecessary kernel_dequeue_signal() nbd_thread_send() does kernel_dequeue_signal() at the end for no reason, it is fine to exit with the pending SIGKILL. Not sure it really needs another kernel_dequeue_signal() inside the main loop, we know that signal_pending() means SIGKILL. But probably we want to clear TIF_SIGPENDING before sock_shutdown().
