perf on 4.1 fails to mmap the perf data file (in __perf_session__process_events) with error code 22 (invalid argument). I believe the JFFS2 file system does not support PROT_READ and MAP_SHARED. How can this be fixed? Can we change from MAP_SHARED to MAP_PRIVATE, or is there a reason to make it shared?
