From 6572bc28de150aaa6ca182eaf3e60c199ba48630 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 19 Sep 2007 15:27:39 +1000 Subject: [PATCH] [XFS] simplify validata_fields Stop using xfs_getattr and a onstack bhv_vattr_t just to get three fields from the underlying inode and opencode copying from the inode fields instead.
