SubjectRe: [PATCH] tracing: Add saved_tgids file to show cached pid to tgid mappings
Hi Michael,

[auto build test ERROR on trace/for-next]
[also build test ERROR on next-20170630]
[cannot apply to tip/perf/core linus/master v4.12-rc7]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Michael-Sartain/tracing-Add-saved_tgids-file-to-show-cached-pid-to-tgid-mappings/20170702-092448
base: https://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git for-next

compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
# save the attached .config to linux build tree
make ARCH=i386
