From 875d1daa7bc683821a4209e1c6aab24909e95217 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Mon, 6 Jun 2022 19:06:17 +0200 Subject: btrfs: simplify parameters of backref iterators The inode reference iterator interface takes parameters that are derived from the context parameter, but as it's a void* type the values are passed individually. Change the ctx type to inode_fs_path as it's the only thing we pass and drop any parameters that are derived from that.
