WARNING: CPU: 1 PID: 9094 at fs/io_uring.c:8884 io_disable_sqo_submit+0x106/0x130 fs/io_uring.c:8884 Call Trace: io_uring_flush+0x28b/0x3a0 fs/io_uring.c:9099 filp_close+0xb4/0x170 fs/open.c:1280 close_fd+0x5c/0x80 fs/file.c:626 __do_sys_close fs/open.c:1299 [inline] __se_sys_close fs/open.c:1297 [inline] __x64_sys_close+0x2f/0xa0 fs/open.c:1297 do_syscall_64+0x2d/0x70 arch/x86/entry/common.c:46 entry_SYSCALL_64_after_hwframe+0x44/0xa9 io_uring's final close() may be triggered by any task not only the creator. It's well handled by io_uring_flush() including SQPOLL case, though a warning in io_disable_sqo_submit() will fallaciously fire by moving this warning out to the only call site that matters.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
