Subject: [PATCH 05/19] Remove find_inferior_in_random
Date: Mon, 20 Nov 2017 16:35:00 -0000	[thread overview]
Message-ID: <1511195683-2055-6-git-send-email-simon.marchi@ericsson.com> (raw)
In-Reply-To: <1511195683-2055-1-git-send-email-simon.marchi@ericsson.com>

From: Simon Marchi <simon.marchi@polymtl.ca>

Replace with find_thread_in_random.

gdb/gdbserver/ChangeLog:

	* inferiors.c (find_inferior_in_random): Remove.
	* inferiors.h (find_inferior_in_random): Remove.
	* linux-low.c (status_pending_p_callback): Return bool, accept
	parameter ptid directly.
	(linux_wait_for_event_filtered): Use find_thread_in_random.
	(linux_wait_1): Likewise.
