From 8ef34723eff08806e3e9c1c756c62a3cb482a3b8 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 5 Nov 2019 15:33:56 -0800 Subject: xfs: add missing early termination checks to record scrubbing functions Scrubbing directories, quotas, and fs counters all involve iterating some collection of metadata items. The per-item scrub functions for these three are missing some of the components they need to be able to check for a fatal signal and terminate early. Per-item scrub functions need to call xchk_should_terminate to look for fatal signals, and they need to check the scrub context's corruption flag because there's no point in continuing a scan once we've decided the data structure is bad. Add both of these where missing. Signed-off-by: Darrick J.
