Please always use memset() if you want to zero initialize something in
the kernel, we had enough trouble with that.
What trouble is that? I've not heard of anything, and we use
={} quite extensively in drm land.
={} initializes only named fields, not padding.
Has that actually happened?
YES! Numerous times!
You wouldn't happen to have links/etc. to the discussion?
I'd like to check them out.
Uff, that was years ago. Just google for something like "mesa memset
hash", there was recently (~ the last year) another discussion because
somebody ran into exactly that problem once more.
Christian.
