Subject: Btrfs: don't get the block_rsv in btrfs_free_tree_block
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d02c9955ded7fc56dd1edc987558b084ccb03eb4;p=linux-beck.git

Btrfs: don't get the block_rsv in btrfs_free_tree_block

Since the durable block rsv stuff has been killed there is no need to get the
block_rsv in btrfs_free_tree_block anymore.
