Subject: [PATCH] t/io_uring: fix 64-bit cast on 32-bit archs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
gcc complains that:
t/io_uring.c: In function ‘init_io_pt’:
t/io_uring.c:618:52: error: left shift count >= width of type [-Werror=shift-count-overflow]
618 | sqe->user_data |= ((unsigned long)s->clock_index << 32);
| ^~
we're shifting more than the size of the type. Cast to a 64-bit value
so that it'll work on 32-bit as well.
Fixes: 7d04588a7663 ("t/io_uring: add support for async-passthru")
