From e1c8af1e02c7893f2d056aa44c4daf59fe0881ed Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 8 Nov 2019 14:57:48 -0800 Subject: xfs: devirtualize ->node_hdr_to_disk Replace the ->node_hdr_to_disk dir ops method with a directly called xfs_da_node_hdr_to_disk helper that takes care of the v4 vs v5 difference.
