Subject: common/dmerror: add some more dmerror routines
X-Git-Tag: v2022.05.01~2647
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=8522cbe6563f679d912afd9d963b8646b87f63c7;p=users%2Fhch%2Fxfstests-dev.git

common/dmerror: add some more dmerror routines

Add functions to the dmerror routine so that we can load both the
error table and the linear table.  This will help us with EIO testing
of copy-on-write.
