This patch changes the output for gfp_flags from being a simple hex value to the actual names. gfp_flags=GFP_ATOMIC instead of gfp_flags=00000020 And even gfp_flags=GFP_KERNEL instead of gfp_flags=000000d0 (Thanks to Frederic Weisbecker for pointing out that the first version had a bad order of GFP masks) [ Impact: more human readable output from tracer ] Acked-by: Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>

* For example, if we have GFP_KERNEL before GFP_USER we wil get:

|
|
* GFP_KERNEL|GFP_HARDWALL
