With the more recent Xorg/mesa version now in sid the deleted objects have a 
different name:

# grep i915 /proc/$(pidof Xorg)/maps

It makes it obvious that the problem is specific to Intel GPUs.

Thanks for checking!  I confirm that on another test system with an AMD GPU I 
do not observe the deleted mappings.

I'm not seeing any such mappings with an AMD GPU. I suspect they might
be from the Mesa i965 driver.


P.S. Please file bugs either upstream or downstream, not both at the
same time.

Package: xserver-xorg-core

Severity: normal


Dear Maintainer,

here is the problem:

# grep /drm /proc/$(pidof Xorg)/maps
7f4afc942000-7f4afc94a000 rw-s  00:05 293242 /drm 
mm object (deleted)

7f4b00b4c000-7f4b00b5 rw-s  00:05 292165 /drm 
mm object (deleted)
7f4b00b52000-7f4b00b53000 rw-s  00:05 292159 /drm 
mm object (deleted)

This is just after the Xorg server has been started by lightdm.
Those deleted mappings should probably not be there and waste memory.
