Subject: btrfs: get fs_info from eb in repair_eb_io_failure
X-Git-Tag: microblaze-v5.4-rc1~510^2~176
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=20a1fbf97e11204e099a95167f1851fc54296a00;p=linux-2.6-microblaze.git

btrfs: get fs_info from eb in repair_eb_io_failure

We can read fs_info from extent buffer and can drop it from the
parameters. As all callsites are updated, add the btrfs_ prefix as the
function is exported.
