Subject: [PATCH 0/8] tracing: further shrinking trace events
Date: Mon, 24 May 2010 16:22:00 +0800 [thread overview]
Message-ID: <4BFA3728.3000701@cn.fujitsu.com> (raw)
patch 1-2: reduce per trace event foot print
patch 3-5: convert some trace events to DEFINE_EVENT
patch 6-8: do some cleanups and thus shrink text size a bit
Save ~5.7K in text and ~2.9K in data:
text data bss dec hex filename
7018612 2034376 7251132 16304120 f8c7f8 vmlinux.o.orig
7012847 2031440 7251132 16295419 f8a5fb vmlinux.o
And save considerable memory allocated by trace_define_event().
