Sorry, no, the fuzz was easy, this breaks the build: fs/io_uring.c: In function ‘io_prep_rw’: fs/io_uring.c:2715:47: error: implicit declaration of function ‘io_file_supports_nowait’; did you mean ‘io_file_supports_async’? [-Werror=implicit-function-declaration] 2715 | ((file->f_flags & O_NONBLOCK) && !io_file_supports_nowait(req, rw))) | ^~~~~~~~~~~~~~~~~~~~~~~ | io_file_supports_async CHK kernel/kheaders_data.tar.xz cc1: some warnings being treated as errors Any hint as to what that function would be in 5.14.y? thanks, greg k-h
