Subject: [PATCH 2/3] reiserfs: use proper little-endian bitops
Date: Mon, 30 May 2011 22:53:14 +0900 [thread overview]
Message-ID: <1306763595-13908-2-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1306763595-13908-1-git-send-email-akinobu.mita@gmail.com>
Using __test_and_{set,clear}_bit_le() with ignoring its return value
can be replaced with __{set,clear}_bit_le().
