Subject: [PATCH 07/19] Remove usage of find_inferior in linux_detach
Date: Mon, 20 Nov 2017 16:35:00 -0000	[thread overview]
Message-ID: <1511195683-2055-8-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 for_each_thread with pid filtering.

gdb/gdbserver/ChangeLog:

	* linux-low.c (linux_detach_lwp_callback): Return void, remove
	args parameter, don't check for pid.
	(linux_detach): Use for_each_thread.
