[GIT PULL] io_uring fixes for 6.6-final

[Jens Axboe]

Hi Linus,

Fix for an issue reported where reading fdinfo could find a NULL thread
as we didn't properly synchronize, and then a disable for the
IOCB_DIO_CALLER_COMP optimization as a recent reported highlighted how
that could lead to deadlocks if the task issued async O_DIRECT writes
and then proceeded to do sync fallocate() calls.

Please pull!
