From b55725974c9d3a5afcdf83daff6fba7d3f91ffca Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 8 Jan 2018 10:51:08 -0800 Subject: xfs: create a new buf_ops pointer to verify structure metadata Expose all metadata structure buffer verifier functions via buf_ops. These will be used by the online scrub mechanism to look for problems with buffers that are already sitting around in memory. Signed-off-by: Darrick J.
