From 44ecd42fab8d23da1a707f513d91f5fc4c122b9b Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 29 Jul 2024 16:22:52 -0700 Subject: [PATCH] xfs: teach online scrub to find directory tree structure problems Source kernel commit: 928b721a11789a9363d6d7c32a1f3166a79f3b5f Create a new scrubber that detects corruptions within the directory tree structure itself. It can detect directories with multiple parents; loops within the directory tree; and directory loops not accessible from the root. Signed-off-by: Darrick J.
