A question for the kernel 'st' coder(s)

About 3 years ago, the backup program amanda was having a problem with
being unable to rewind a tape drive, while mt worked just fine.

The amanda version used an ioctl call rather than a higher level
interface. At the time, it was fixed by using what was a non-std
syntax according to the docs, but it worked. My memory is getting
faint, but it seems that 2 of the vars in the call had to be
interchanged, or some such. Till somewhere about the 2.6.3, maybe
2.6.4 time frame I believe. Now amanda seems to have lost its
ability to rewind a tape, and must rely on the ejection and loading
of a tape before it can read the label and verify that this is indeed
the correct tape for this amdump run.

Was there a bit of cleanup in the st code that brought that calls
syntax into line with the docs in moderately recent history?

Where would I find the docs on this particular call, as it exists
today for 2.6.5+ kernels?
