Subject: btrfs: make btrfs_run_delalloc_range take btrfs_inode
X-Git-Tag: v5.15~2817^2~108
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=98456b9c46c140275b0fe81970ddfad250c68ed4;p=platform%2Fkernel%2Flinux-starfive.git

btrfs: make btrfs_run_delalloc_range take btrfs_inode

All children now take btrfs_inode so convert it to taking it as a
parameter as well.
