I believe we agreed on making drivers responsible for releasing buff, so full audit requires addressing existing -ENOBUFS-aware drivers (intel), removing release from core and then teach rest of the drivers to handle -ENOBUFS properly. Basically this is what you initially proposed but with bigger driver scope, but maybe for now stick to addressing drivers that Sashiko pointed out (gve?). Bjorn might be OoO today but this is what I had in my mind after the meeting, without revisiting the links. > > Regards, > Marcin
