Subject: [Qemu-devel] [PATCH v2 2/2] test-bitmap: add test for bitmap_set
Date: Wed, 17 Jul 2019 15:11:14 +0800 [thread overview]
Message-ID: <20190717071114.14772-3-richardw.yang@linux.intel.com> (raw)
In-Reply-To: <20190717071114.14772-1-richardw.yang@linux.intel.com>
Add a test for bitmap_set. There are three cases:
* Both start and end is BITS_PER_LONG aligned
* Only start is BITS_PER_LONG aligned
* Only end is BITS_PER_LONG aligned
Signed-off-by: Wei Yang <richardw.yang@linux.intel.com>
