Hi Linus,
Random assortment of fixes, either heading to stable or fixing an issue
introduced in this series.
- Fix an issue with discontig page checking for IORING_SETUP_NO_MMAP
- Fix an issue with not allowing IORING_SETUP_NO_MMAP also disallowing
mmap'ed buffer rings
- Fix an issue with deferred release of memory mapped pages
- Fix a lockdep issue with IORING_SETUP_NO_MMAP
- Use fget/fput consistently, even from our sync system calls. No real
issue here, but if we were ever to allow closing io_uring descriptors
it would be required. Let's play it safe and just use the full ref
counted versions upfront. Most uses of io_uring are threaded anyway,
and hence already doing the full version underneath.
Please pull!
