Subject: [PATCH xserver 50/51] present: actually return the created notifies
|
|
|
|
present_create_notifies() creates an array of notifies but never returns
|
|
them to the caller, despite them being passed individually to
|
|
present_add_window_notify(). The caller proceeds with a NULL notifies
|
|
array, eventually causing an OOB in present_vblank_notify() when
|
|
vblank->notifies is NULL.
|
|
