Subject: btrfs: get fs_info from trans in insert_ptr
X-Git-Tag: v5.2-rc1~163^2~79
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=6ad3cf6df0963845a681d39792822255598d68e2;p=linux.git

btrfs: get fs_info from trans in insert_ptr

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