From d519da41e2b789f2cbd705cd8cec0bb92be4838d Mon Sep 17 00:00:00 2001 From: Marco Benatto Date: Fri, 1 Feb 2019 09:12:20 -0800 Subject: xfs: Introduce XFS_PTAG_VERIFIER_ERROR panic mask Currently we have a few PTAGs in place allowing us to transform a filesystem error in a BUG() call. However, we don't have a panic tag for corrupt metadata, so introduce XFS_PTAG_VERIFIER_ERROR so that the administrator can use the fs.xfs.panic_mask sysctl knob to convert any error detected by buffer verifiers into a kernel panic.
