This series allows to selectively enable/disable polling for completions
in the block layer on a per-I/O basis.  For this it resurrects the
preadv2/pwritev2 syscalls that Milosz prepared a while ago (and which
are much simpler now due to VFS changes that happened in the meantime).
That approach also had a man page update prepared, which I will resubmit
with the current flags once this series makes it in.

It would be helpful for reviewers if you submitted the man page at the
same time, in my opinion.

Ok.

Do you have any plans on adding polling support to the buffered path?

How would that even make sense?
