Hi everyone,
this posting has been out for 2 weeks now, without any replies except
for Jeff reminding of the missing reviews he already gave me in the
previous version.
Canwe make some progress on this? Especially as all the aio bits
have gotten reviews from Jeff.

Hi all,
this series adds support for the IOCB_CMD_POLL operation to poll for the
readyness of file descriptors using the aio subsystem. The API is based
on patches that existed in RHAS2.1 and RHEL3, which means it already is
supported by libaio. To implement the poll support efficiently new

A bisect lands on: eventfd: switch to ->poll_mask. That's not super
helpful, though. I did run the ltp eventfd2 tests, and they all pass.
FYI, this kernel has issues. It will boot up, but I don't have
networking, and even rebooting doesn't succeed. I'm looking into it.

Due to the current events:
With KPTI enabled
And of coure I should have added linux-api to the series.
Note that the libaio patches include documenting io_pgetevents in the
io_getevents man page.
