Hi Jérôme, Ben and Jason,
below is a series against the hmm tree which fixes up the mmap_sem
locking in nouveau and while at it also removes leftover legacy HMM APIs
only used by nouveau.
The first 4 patches are a bug fix for nouveau, which I suspect should
go into this merge window even if the code is marked as staging, just
to avoid people copying the breakage.
Changes since v2:
- new patch from Jason to document FAULT_FLAG_ALLOW_RETRY semantics
better
- remove -EAGAIN handling in nouveau earlier
I don't see Ralph's tested by, do you think it changed enough to
require testing again? If so, Ralph would you be so kind?
In any event, I'm sending this into linux-next and intend to forward
the first four next week.
Thanks,
Jason
I have been testing Christoph's v3 with my set of v2 changes so
feel free to add my tested-by.
