Running into a problem when killing glthreads with Ctrl-C. Normally this would invoke the release() method and clean up buffers, locks etc. Unfortunately this doesn't work so well with threads - the release method is being called only once despite the 3 processes (threads) that are being killed. Unfortunately the drm module makes use of current->pid extensively, so it really expects each thread to invoke a release() call.
This was discussed here a while ago, and fixed in the kernel DRM for DRM 4.2 at least. There are two methods that matter here
->flush is called each time close() occurs ->release is called on the final close and disposal of a file
Hmm, I remeber the discussion. I thought we were pretty much in sync with the kernel -- I guess this must be 2.4, right?
So you get open ->open close ->flush, ->release
open ->open fork close ->flush close ->flush. ->release
So, was the gist of the fix to simply relocate the current release() stuff to flush()? I'm going to go & read the code now.
