tracing: Add "gfp_t" support in synthetic_events
Add "gfp_t" support in synthetic_events, then the "gfp_t" type parameter in some functions can be traced. Prints the gfp flags as hex in addition to the human-readable flag string. Example output: whoopsie-630 [000] ...1 78.969452: testevent: bar=b20 (GFP_ATOMIC|__GFP_ZERO) rcuc/0-11 [000] ...1 81.097555: testevent: bar=a20 (GFP_ATOMIC) rcuc/0-11 [000] ...1 81.583123: testevent: bar=a20 (GFP_ATOMIC) Link: http://lkml.kernel.org/r/20190712015308.9908-1-zhengjun.xing@linux.intel.com Signed-off-by:Zhengjun Xing <zhengjun.xing@linux.intel.com> [ Added printing of flag names ] Signed-off-by:
