From c715e155c94ba0b3657820d676ec3c7213a5ce81 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Mon, 31 Mar 2014 14:52:14 +0100 Subject: Btrfs: send, build path string only once in send_hole There's no point building the path string in each iteration of the send_hole loop, as it produces always the same string.
