Subject: [PATCH v1 0/3] mm,hwpoison: fix sending SIGBUS for Action Required MCE
Hi,
I wrote this patchset to materialize what I think is the current
allowable solution mentioned by the previous discussion [1].
I simply borrowed Tony's mutex patch and Aili's return code patch,
then I queued another one to find error virtual address in the best
effort manner. I know that this is not a perfect solution, but
should work for some typical case.
My simple testing showed this patchset seems to work as intended,
but if you have the related testcases, could you please test and
let me have some feedback?
Thanks,
Naoya Horiguchi
