From 7878cba9f0037f5599004b03a1260b32d9050360 Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Fri, 26 Jun 2009 15:37:49 +0200 Subject: block: Create bip slabs with embedded integrity vectors This patch restores stacking ability to the block layer integrity infrastructure by creating a set of dedicated bip slabs. Each bip slab has an embedded bio_vec array at the end. This cuts down on memory allocations and also simplifies the code compared to the original bvec version. Only the largest bip slab is backed by a mempool. The pool is contained in the bio_set so stacking drivers can ensure forward progress. Signed-off-by: Martin K.
