Subject: [PATCH 2/3] writeback: Export inode_io_list_del()
References: bsc#1168423
Git-commit: 4301efa4c7cca11556dd89899eee066d49b47bf7
Patch-mainline: v5.8-rc1

Ext4 needs to remove inode from writeback lists after it is out of
visibility of its journalling machinery (which can still dirty the
inode). Export inode_io_list_del() for it.
