Ok, I thought that you were talking about per-process data being in the
file descriptor.
No, Linux has absolutely no concept of per-process data in driver, and
if you think of it that would be rather bogus anyway (e.g. a driver opening
the same device multiple times)
though, some people use it for that purpose (e.g. in the original posting).
it might not be such a bad idea..
I don't see why the device entrypoints shouldn't have that argument
available.. (file descriptor by which we are getting here)
As long as it can take account of the fact that not all accesses come
via an FD
(e.g mounted disks).
