From 91fb9afc0847926ef6ea7695b8125c8fbe7974d6 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 17 Oct 2017 21:37:34 -0700 Subject: xfs: create inode pointer verifiers Create some helper functions to check that inode pointers point to somewhere within the filesystem and not at the static AG metadata. Move xfs_internal_inum and create a directory inode check function. We will use these functions in scrub and elsewhere. Signed-off-by: Darrick J.
