Subject: btrfs: alloc_reserved_file_extent trace point should use extent_root
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2b2e27eb9230686a0e8d933b2933327a5c88671a;p=linux-beck.git

btrfs: alloc_reserved_file_extent trace point should use extent_root

Even though a separate root is passed in, we're still operating on the
extent root.  Let's use that for the trace point.
