Subject: btrfs: Remove fs_info argument from add_new_free_space
X-Git-Tag: 4.18-fixes-smb3~19^2~96
X-Git-Url: http://git.samba.org/samba.git/?p=sfrench%2Fcifs-2.6.git;a=commitdiff_plain;h=4457c1c702fa1cb2f032bae6dfa0dd2f84ff2b5c

btrfs: Remove fs_info argument from add_new_free_space

This function also takes a btrfs_block_group_cache which contains a
referene to the fs_info. So use that and remove the extra argument.
