Hi all, After merging the block tree, today's linux-next build (arm multi_v7_defconfig) produced this warning: fs/io_uring.c: In function '__io_uring_show_fdinfo': fs/io_uring.c:6558:32: warning: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'size_t' {aka 'unsigned int'} [-Wformat=] 6558 | seq_printf(m, "%5u: 0x%llx/%lu\n", i, buf->ubuf, buf->len); | ~~^ ~~~~~~~~ | | | | long unsigned int size_t {aka unsigned int} | %u Introduced by commit 0380f1b6d0c6 ("io_uring: add ->show_fdinfo() for the io_uring file descriptor") -- Cheers, Stephen Rothwell
