Subject: btrfs: reduce parameters of btrfs_pin_reserved_extent
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f863c50277c57cdbd6b0d1bbddb2b19a25016151;p=linux.git

btrfs: reduce parameters of btrfs_pin_reserved_extent

There is only one caller of btrfs_pin_reserved_extent that expands the
parameters to extent buffer members. We can simply pass the extent
buffer instead.
