Subject: [GIT PULL] io_uring fixes for 6.6-final
Date: Fri, 27 Oct 2023 13:53:52 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
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!
