Re: vm_operations (was: Re: release not called for my driver?)

[Stephen Williams <steve@icarus.com>]

As far as I can tell, the Linux kernel device driver interface is very
poorly documented. The Rubinni book is as close as one gets to documentation,
but that does not cover much of vm behavior, and certainly doesn't cover
the cases you and I are handling.

Example code may well be the best documentation (thanks, Alan) but a
driver for a complex dvice can get a bit opaque and what are really needed
are contrived and heavily commented examples.

Oh well, Linux drivers are part of my job description so I do have the
time to figure things out. It just would be nice if the people who add these
nifty-neato interfaces in the kernel actually took the time to describe
them.
