Subject: btrfs: get fs_info from block group in write_pinned_extent_entries
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6701bdb39ceb48d9b155c2b7f989c250140d6e45;p=openwrt%2Fstaging%2Fblogic.git

btrfs: get fs_info from block group in write_pinned_extent_entries

We can read fs_info from the block group cache structure and can drop it
from the parameters.
