Subject: btrfs: Remove redundant assignment in btrfs_get_extent_fiemap
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=02950af4e3b7dbbb9c5483da4d93d53ed0fd27a8;p=linux.git

btrfs: Remove redundant assignment in btrfs_get_extent_fiemap

hole_len is only used if the hole falls within the requested range. Make
that explicitly clear by only assigning in the corresponding branch.
