From: Miao Xie Date: Mon, 26 Nov 2012 08:40:43 +0000 (+0000) Subject: Btrfs: pass root object into btrfs_ioctl_{start, wait}_sync() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9a8c28bec1b40e934ed28149b7eaa7d2fafed92d;p=openwrt%2Fstaging%2Fblogic.git Btrfs: pass root object into btrfs_ioctl_{start, wait}_sync() Since we have gotten the root in the caller, just pass it into btrfs_ioctl_{start, wait}_sync() directly.
