From 081a8ae2a54e85ddd77db77d50b1a04b3c4731c9 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 21 Feb 2019 07:53:20 -0800 Subject: xfs: fix uninitialized error variable A previous commit removed the initialization of variable 'error' to zero, and can cause a bogus error return. This occurs when error contains a non-zero garbage value and the call to xchk_should_terminate detects a pending fatal signal and checks for a zero error before setting it to -EAGAIN. Fix the issue by initializing error to zero. Fixes: b9454fe056bd ("xfs: clean up the inode cluster checking in the inobt scrub") Signed-off-by: Colin Ian King Reviewed-by: Darrick J.
