Cover letter [PATCH 0/3] few memory offlining enhancements
This has been posted as an RFC [1]. There was a general agreement for these patches. I hope I have addressed all the review feedback.
Original cover:
I have been chasing memory offlining not making progress recently. On the way I have noticed few weird decisions in the code. The migration itself is restricted without a reasonable justification and the retry loop around the migration is quite messy. This is addressed by patch 1 and patch 2.
Patch 3 is targeting on the faultaround code which has been a hot candidate for the initial issue reported upstream [2] and that I am debugging internally. It turned out to be not the main contributor in the end but I believe we should address it regardless. See the patch description for more details.
