Subject: Btrfs: don't try and free ebs twice in log replay
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5ec8dca7617b77afb0e3c7e6271089172b498546;p=openwrt%2Fstaging%2Fblogic.git

Btrfs: don't try and free ebs twice in log replay

This work is done by btrfs_free_path() anyway so there's no need for this
duplicate work.  Thanks,
