At that time AFAIK, there was also a problem with wong timeouts
for some people and I did never get a mailk that did help to find the
reason.

OK, then it should work this way:
#ifdef USER_HZ
tmo *= USER_HZ;
if (tmo)
tmo += USER_HZ/2;
#else
tmo *= HZ;
if (tmo)
tmo += HZ/2;
#endif

Then this
#if LINUX_VERSION_CODE <= 0x020600
if (use_ata)
#endif
for (i = 0; i <= 25; i++) {
js_snprintf(devname, sizeof (devname), "/dev/hd%c", i+'a');
should work....

Besides the fact that EROFS is wrong here, it would be interesting to know
what happens if opening readonly.....

It would be legal if /dev/ was on a ro FS and /dev/hdg was a plain file.

I don't care about libburn, it is so broken that it does not even complete
it's "configure" run:
checking for a BSD-compatible install... /opt/sfw/bin/ginstall -c
./configure: line 19396: syntax error near unexpected token `in'
./configure: line 19396: `for ac_header in'
So it cannot even compile on Linux.....

As this is not doable before you did scan, it would need to stay similar to how
it is.
