From 9d4b0a129a0d081821f21edccad154f8e2a1b747 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 15 Jul 2022 15:45:22 -0400 Subject: btrfs: simplify arguments of btrfs_update_space_info and rename This function has grown a bunch of new arguments, and it just boils down to passing in all the block group fields as arguments. Simplify this by passing in the block group itself and updating the space_info fields based on the block group fields directly.
