From 9cfb9b47479e237d217dbcfafe034cbf98f45909 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 8 Jan 2018 10:51:06 -0800 Subject: xfs: provide a centralized method for verifying inline fork data Replace the current haphazard dir2 shortform verifier callsites with a centralized verifier function that can be called either with the default verifier functions or with a custom set. This helps us strengthen integrity checking while providing us with flexibility for repair tools. xfs_repair wants this to be able to supply its own verifier functions when trying to fix possibly corrupt metadata.
