Subject: [PATCH v2 0/5] perf: Untangle aux refcounting

Hi Peter,

Here's a long overdue update of the previous attempt to untangle the
aux buffer unmapping and deallocation. Most of the work is in 2/5.

Alexander Shishkin (5):
  perf: Refuse to begin aux transaction after aux_mmap_count drops
  perf: Free aux pages in unmap path
  perf: Document aux api usage
  perf/x86/intel/pt: Move transaction start/stop to pmu start/stop
    callbacks
  perf/x86/intel/bts: Move transaction start/stop to start/stop
    callbacks
