While testing patches in this series I noticed this:

[root@jouet ~]# perf mem record -a
Error: unknown switch `a'

Usage: perf mem record [<options>] [<command>]
or: perf mem record [<options>] -- <command> [<options>]

-e, --event <event> event selector. use 'perf mem record -e list' to list available events
-v, --verbose be more verbose (show counter open errors, etc)

[root@jouet ~]# perf mem record -- -a
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 3.149 MB (173 samples) ]

[root@jouet ~]#

Can't we imply the -- after 'record', i.e pass everything after 'record'
to the underlying 'perf record' call?
