[PATCH 02/13] perf header: Bump up the max number of command line args allowed

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

We need to do some upper limit validation, bump up the arbitrary limit
as per suggestion of Sashiko about command line wildcard expansion
ending up with more than 32768 args.
