From b6ac23af2c66e114d3a87ef28d56f1ceec283007 Mon Sep 17 00:00:00 2001 From: Divyesh Shah Date: Thu, 15 Apr 2010 08:54:59 +0200 Subject: [PATCH] blkio: fix for modular blk-cgroup build After merging the block tree, 20100414's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "get_gendisk" [block/blk-cgroup.ko] undefined! ERROR: "sched_clock" [block/blk-cgroup.ko] undefined! This happens because the two symbols aren't exported and hence not available when blk-cgroup code is built as a module. I've tried to stay consistent with the use of EXPORT_SYMBOL or EXPORT_SYMBOL_GPL with the other symbols in the respective files.
