I'm a bit pessimistic about this patch. What if we have a root filesystem on an SD card, or, what is a more common case, on an eMMC? How is it going to be handled?
This is handled for sure. I have verified this case and I agree that this is likely a common case.
In principle, every mmc/sd requests handled in issue_rq (block.c), will unless the host is not already resumed, do a "sync" of the resume work.
I see no trace of taking this into account in here so it's a NAK for now from my side. Thanks, Vitaly
