From 21ec54168b368f1a98097dee00625ec8ec2d47f3 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 17 Oct 2017 21:37:32 -0700 Subject: xfs: create block pointer check functions Create some helper functions to check that a block pointer points within the filesystem (or AG) and doesn't point at static metadata. We will use this for scrub. Signed-off-by: Darrick J.
