just auto updated from 5.13.16 to 5.13.17, and suddenly my fixed
file registrations fail with EOPNOTSUPP using liburing 2.0.
static inline struct io_uring ring;
static inline int *socketfds;
// ...
void enableFD(int fd)
{
int result = io_uring_register_files_update(&ring, fd,
&(socketfds[fd] = fd), 1);
printf("enableFD, result = %d\n", result);
}
maybe this is due to the below and related work that
occurred at the end of 5.13 and liburing got out of sync?
https://github.com/torvalds/linux/commit/992da01aa932b432ef8dc3885fa76415b5dbe43f#diff-79ffab63f24ef28eec3badbc8769e2a23e0475ab1fbe390207269ece944a0824
and can't use liburing 2.1 because of the api changes since 5.13.
