Subject: btrfs: get fs_info from trans in btrfs_run_dev_stats
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=196c9d8de8389643318c22259fd5bcfccbc7fb91;p=linux.git

btrfs: get fs_info from trans in btrfs_run_dev_stats

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