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
