SubjectRe: [PATCH v2 6/9] trace_uprobe: Support SDT markers having reference count (semaphore)
Hi Ravi,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on tip/perf/core]
[also build test WARNING on v4.16 next-20180404]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__

sparse warnings: (new ones prefixed by >>)

kernel/trace/trace.h:1298:38: sparse: incorrect type in argument 1 (different address spaces) @@ expected struct event_filter *filter @@ got struct event_filtstruct event_filter *filter @@
kernel/trace/trace.h:1298:38: expected struct event_filter *filter

>> kernel/trace/trace_uprobe.c:1001:6: sparse: symbol 'trace_uprobe_mmap' was not declared. Should it be static?

Please review and possibly fold the followup patch.
