Subject: [Qemu-devel] [PULL 07/12] test-bitmap: add test for bitmap_set
Date: Sat, 20 Jul 2019 17:18:41 +0200 [thread overview]
Message-ID: <20190720151846.7450-8-pbonzini@redhat.com> (raw)
In-Reply-To: <20190720151846.7450-1-pbonzini@redhat.com>
From: Wei Yang <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
