 =item eio_readahead (int fd, off_t offset, size_t length, int pri, eio_cb cb, void *data)
 Calls C<readahead(2)>. If the syscall is missing, then the call is
 emulated by simply reading the data (currently in 64kiB chunks).
+=item eio_syncfs (int fd, int pri, eio_cb cb, void *data)
+Calls Linux' C<syncfs> syscall, if available. Returns C<-1> and sets
+C<errno> to C<ENOSYS> if the call is missing I<but still calls sync()>,
+if the C<fd> is C<< >= 0 >>, so you can probe for the availability of the
+syscall with a negative C<fd> argument and checking for C<-1/ENOSYS>.
 =item eio_sync_file_range (int fd, off_t offset, size_t nbytes, unsigned int flags, int pri, eio_cb cb, void *data)
 Calls C<sync_file_range>. If the syscall is missing, then this is the same
 as calling C<fdatasync>.
