Date: Mon, 11 Jul 2011 01:46:50 -0600 From: Jim Cromie <jim.cromie@...il.com> To: jbaron@...hat.com Cc: linux-kernel@...r.kernel.org, bvanassche@....org, joe@...ches.com, gregkh@...e.de, gnb@...h.org, Jim Cromie <jim.cromie@...il.com> Subject: [PATCH 15/21] dynamic_debug: describe_flags with '=[ptmfl]*' Describe flags in text using =<flag-chars>. This has better mnemonics than the current dash-unless-flags, it says "Flags are = <flag-chars>", and =<flags> is more selective in a grep; '=' will not show up in module or filenames, nor in line-ranges. This isnt yet optimal; "grep ' = ' control" reports on a couple dozen format-strings, this could be avoided by altering describe_flags() to emit '-' or '_' for empty flags, such that the grep for empty flags would be '=_'. TBD.
