Subject: btrfs: Don't pass fs_info arg to btrfs_start_dirty_block_groups
X-Git-Tag: v4.19~990^2~176
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=21217054203cd10f26ba133352046895c16cd3de;p=platform%2Fkernel%2Flinux-rpi.git

btrfs: Don't pass fs_info arg to btrfs_start_dirty_block_groups

It can be referenced from the passed transaction so no point in passing
it as a function argument. No functional changes.
