From 821de3a27bf33f11ec878562577c586cd5f83c64 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 8 May 2007 19:12:23 +0200 Subject: [PATCH] [PATCH] ll_rw_blk: fix missing bounce in blk_rq_map_kern() I think we might just need the blk_map_kern users now. For the async execute I added the bounce code already and the block SG_IO has it atleady. I think the blk_map_kern bounce code got dropped because we thought the correct gfp_t would be passed in. But I think all we need is the patch below and all the paths are take care of. The patch is not tested. Patch was made against scsi-misc. The last place that is sending non sg commands may just be md/dm-emc.c but that is is just waiting on alasdair to take some patches that fix that and a bunch of junk in there including adding bounce support. If the patch below is ok though and dm-emc finally gets converted then it will have sg and bonce buffer support.
