No upstream commit exists. This imports the io_uring codebase from 5.15.85, wholesale. Changes from that code base: - Drop IOCB_ALLOC_CACHE, we don't have that in 5.10. - Drop MKDIRAT/SYMLINKAT/LINKAT. Would require further VFS backports, and we don't support these in 5.10 to begin with. - sock_from_file() old style calling convention. - Use compat_get_bitmap() only for CONFIG_COMPAT=y Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
