We already do check for handle syscall. Since glibc doesn't have the
this syscall yet, I added the check in virtio-9p-handle.c as below
#ifdef __NR_name_to_handle_at
static inline int name_to_handle(int dirfd, const char *name,
struct file_handle *fh, int *mnt_id, int flags)
{
return syscall(__NR_name_to_handle_at, dirfd, name, fh, mnt_id, flags);
}
#else
static inline int name_to_handle(int dirfd, const char *name,
struct file_handle *fh, int *mnt_id, int flags)
{
errno = ENOSYS;
return -1;
}
