From df3093907ccc718459c54c99da29dd774af41186 Mon Sep 17 00:00:00 2001 From: Carlos Maiolino Date: Wed, 18 May 2016 11:05:33 +1000 Subject: xfs: add configurable error support to metadata buffers With the error configuration handle for async metadata write errors in place, we can now add initial support to the IO error processing in xfs_buf_iodone_error(). Add an infrastructure function to look up the configuration handle, and rearrange the error handling to prepare the way for different error handling conigurations to be used.
