Subject: btrfs: Remove fs_info argument from __remove_from_free_space_tree
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c31683a6efe5517043c23eada0647c1535f865fe;p=openwrt%2Fstaging%2Fblogic.git

btrfs: Remove fs_info argument from __remove_from_free_space_tree

This function takes a transaction handle which holds a reference to
fs_info. So use that and remove the extra argument.
