Subject: btrfs: get fs_info from trans in btrfs_write_dirty_block_groups
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5742d15fa76adfc833642f9c24f7c31c9b1a1646;p=linux.git

btrfs: get fs_info from trans in btrfs_write_dirty_block_groups

We can read fs_info from the transaction and can drop it from the
parameters.
