From fbb704efb784e2c8418e34dc3013af76bdd58101 Mon Sep 17 00:00:00 2001 From: raz ben yehuda Date: Tue, 16 Jun 2009 17:02:05 +1000 Subject: [PATCH] md: raid0 :Enables chunk size other than powers of 2. Maintain two flows, one for pow2 chunk sizes (which uses masks and shift), and a flow for the general case (which uses sector_div). This is for the sake of performance. - introduce map_sector and is_io_in_chunk_boundary to encapsulate those two flows better for raid0_make_request - fix blk_mergeable to support the two flows.
