Message-Id: <20081024144036K.fujita.tomonori@lab.ntt.co.jp> Date: Fri, 24 Oct 2008 14:41:09 +0900 From: FUJITA Tomonori <fujita.tomonori@....ntt.co.jp> To: linuxppc-dev@...abs.org Cc: paulus@...ba.org, benh@...nel.crashing.org, jens.axboe@...cle.com, linux-kernel@...r.kernel.org Subject: [PATCH] powerpc: remove dead BIO_VMERGE_BOUNDARY definition The block layer dropped the virtual merge feature (b8b3e16cfe6435d961f6aaebcfd52a1ff2a988c5). BIO_VMERGE_BOUNDARY definition is meaningless now (For POWER, BIO_VMERGE_BOUNDARY has been meaningless for a long time since POWER disables the virtual merge feature).
