I think we decided that commit 0a31bc97c80c3fa87b32c091d9a930ac19cd0c40 Author: Johannes Weiner <hannes@xxxxxxxxxxx> Date: Fri Aug 8 14:19:22 2014 -0700 mm: memcontrol: rewrite uncharge API was the likely candidate (given that it was the only change to mm/shmemfs.c in the regresssing time frame). -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
