From ce5028cfe3ca48695b6a128638fe224426d37ebe Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 27 Feb 2014 15:23:10 +1100 Subject: xfs: modify verifiers to differentiate CRC from other errors Modify all read & write verifiers to differentiate between CRC errors and other inconsistencies. This sets the appropriate error number on bp->b_error, and then calls xfs_verifier_error() if something went wrong. That function will issue the appropriate message to the user.
