Subject: [PATCH] io_uring: Add io_cqring_offset flags
Add support for displaying struct io_cqring_offsets.flags introduced
by Linux kernel commits v5.8-rc1~190^2~22 and v5.8-rc1~190^2~21.
* types/io_uring.h (struct_io_cqring_offsets): Replace resv array
with flags, resv1, and resv2 fields.
* xlat/uring_cqring_flags.in: New file.
* configure.ac (AC_CHECK_MEMBERS): Check struct io_cqring_offsets.flags.
* io_uring.c: Include "xlat/uring_cqring_flags.h".
(SYS_FUNC(io_uring_setup)): Replace printing of the resv array
of struct io_cqring_offsets with flags, resv1, and resv2 fields.
* tests/io_uring_setup.c: Check it.

From fded17c15bca4150165f899cc47f67bab963d9a7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] io_uring: Remove struct io_cqring_offsets compile time
asserts
The generated types/check-io_uring.c already checks the kernel's struct
io_cqring_offsets for compatibility with the strace definition so
there's no need for manual checks.
* io_uring.c [HAVE_STRUCT_IO_CQRING_OFFSETS]: Remove static_asserts.

Subject: [PATCH] uring: fix build against 5.8 libc-headers
To get strace building against v5.8 headers before the next
version of strace is released, we need to copy in a bootstrapped
file from the latest git (xlat/uring_cqring_flags.h) and remove
remove unnecessary asserts for v5.8+ (in a similar manner to the
main strace repository).
Upstream-status: inappropriate. oe specific (upstream builds bootstrap)
