Can you please explain, how exactly O_TMPFILE functionality you asking for relates to the /proc ?...

Thanks for looking into this, BTW! O_TMPFILE is the main thing that seems to be missing. Cheers, Rafael

...utputBuffer creation and commit. I don't think that is a code path where that is possible right now, but it would be an easy thing to miss in a code review. I was hopping the OS could help us manage the temporary file so that there was no way to accidentally leave it behind. On linux there is O_TMPFILE, which allows us to create a file with no name in the file system. A name can be given with linkat. Unfortunately we can't use linkat(fd, "", AT_FDCWD, "destination", AT_EMPTY_PATH) Without special permissions and have instead to depend on proc: linkat(AT_FDCWD, "/p...

These changes are based on Jason's latest hmm branch. Patch 1 was previously posted here [1] but was dropped from the orginal series. Hopefully, the tests will reduce concerns about edge conditions. I'm sure more tests could be usefully added but I thought this was a good starting point. [1] https://lore.kernel.org/linux-mm/20190726005650.2566-6-rcampbell at nvidia.com/ Ralph Campbell

This series adds new functions to the mmu interval notifier API to allow device drivers with MMUs to dynamically mirror a process' page tables based on device faults and invalidation callbacks. The Nouveau driver is updated to use the extended API and a set of stand alone self tests is added to help validate and maintain correctness. The patches are based on linux-5.5.0-rc6 and are for
