Subject: [PATCH] ReuseFutureTest: do not use an offset when writing to an
eventfd
Eventfd's does not support seeking. This is also invalid code:
int main() {
int64_t b = 42;
int efd = eventfd(0, 0);
if (efd < 0) err(EXIT_FAILURE, "creating eventfd failed");
ssize_t res = pwrite(efd, &b, sizeof(b), 0);
if (res != sizeof(b)) err(EXIT_FAILURE, "pwrite to evfd failed");
}
