From: Qu Wenruo Date: Fri, 28 Feb 2014 02:46:08 +0000 (+0800) Subject: btrfs: Replace fs_info->submit_workers with btrfs_workqueue. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a8c93d4ef6f6727764a61a2ee1c1878a755637c5;p=linux-beck.git btrfs: Replace fs_info->submit_workers with btrfs_workqueue. Much like the fs_info->workers, replace the fs_info->submit_workers use the same btrfs_workqueue.
