Subject: [PATCH v3 4/7] arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}
Date: Wed, 27 Apr 2011 22:20:08 +0900 [thread overview]
Message-ID: <1303910411-15793-5-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1303910411-15793-1-git-send-email-akinobu.mita@gmail.com>
By the previous style change, CONFIG_GENERIC_FIND_NEXT_BIT,
CONFIG_GENERIC_FIND_BIT_LE, and CONFIG_GENERIC_FIND_LAST_BIT are not used
to test for existence of find bitops anymore.
