Subject: mesa: Ensure object refcount is null when destroying the buffer.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=829d9bb7334ffea0d5d0c4076dd75c41525fae0c;p=mesa.git

mesa: Ensure object refcount is null when destroying the buffer.

Lets see if this is not too pedantic. Obj pointers are never exposed to
GL apps so it should be possible to get this right.

Furthermore apps with GL widgets and test suits create and destroy many
contexts and objects, so bad reference counting is not really an option.
