Subject: btrfs: tree-checker: get fs_info from eb in file_extent_err
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1fd715ffdd14870307c8cd6965c454d928b66d40;p=openwrt%2Fstaging%2Fblogic.git

btrfs: tree-checker: get fs_info from eb in file_extent_err

We can read fs_info from extent buffer and can drop it from the
parameters.
