Subject: [PATCH 3.10 12/38] dm space map metadata: fix sm_bootstrap_get_nr_blocks()
Date: Tue,  6 Jan 2015 17:50:24 -0800	[thread overview]
Message-ID: <20150107014954.456347575@linuxfoundation.org> (raw)
In-Reply-To: <20150107014952.440109372@linuxfoundation.org>

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit c1c6156fe4d4577444b769d7edd5dd503e57bbc9 upstream.

This function isn't right and it causes a static checker warning:

	drivers/md/dm-thin.c:3016 maybe_resize_data_dev()
	error: potentially using uninitialized 'sb_data_size'.

It should set "*count" and return zero on success the same as the
sm_metadata_get_nr_blocks() function does earlier.

Fixes: 3241b1d3e0aa ('dm: add persistent data library')
