Sorry, it appears the issue has not been fixed. The message "radeon: Failed to allocate a buffer" no longer prints, but the original radeon_gem_object_create message still spams dmesg and kern.log.
Did you restart X after building Mesa with the patch?
Wow, I'm an idiot. Yeah, everything is completely fixed after restarting X. No side effects or log spam. Thank you based Michel.
