From 98493ff878859eb0adefbc57a49ad47a92dfd252 Mon Sep 17 00:00:00 2001 From: Allison Henderson Date: Mon, 22 Apr 2024 09:47:38 -0700 Subject: xfs: add parent pointer support to attribute code Add the new parent attribute type. XFS_ATTR_PARENT is used only for parent pointer entries; it uses reserved blocks like XFS_ATTR_ROOT.
