Thanks for posting this.

Given this is going to linux-edac, probably should mention
this is QEMU based error injection.  For cross postings
between kernel related and qemu lists I tend to stick
qemu in the [] of the patch description.

With a few minor tweaks to build files, this is on my cxl gitlab qemu staging
branch as that happens to have other injection stuff (this obviously has little
to do with CXL!)

http://gitlab.com/jic23/qemu/ cxl-2024-06-21

Note I haven't tested that branch beyond a quick boot test, so it might get
some revisions early next week.
