Hi,
I updated the series based on Boris's review. I folded 2/3 and 3/3 into one patch, updated description, added some refactored and rebased onto v5.12. There's no essential change in how the problem is solved.
v1: https://lore.kernel.org/linux-mm/20210412224320.1747638-1-nao.horiguchi@gmail.com/ v2 (only 3/3 is posted): https://lore.kernel.org/linux-mm/20210419023658.GA1962954@u2004/ v3: https://lore.kernel.org/linux-mm/20210421005728.1994268-1-nao.horiguchi@gmail.com/
Thanks, Naoya Horiguchi

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.
