[PATCH] perf: do not flush maps on COMM for perf report

This fixes a long-standing bug caused by the lack of separate COMM and EXEC record types, which makes perf report lose track of symbols when a process renames itself. With this fix (suggested by Stephane Eranian), a COMM (rename) no longer flushes the maps, which is the correct behavior. An EXEC

Hi all, After Dave Airlie blew through a few days to track down a deadlock at boot-up when handing over from the firmware fb to the kms/drm framebuffer driver (1), I've figured that lockdep /should/ have caught this. And indeed, by adding proper annotations to the console_lock it complains
