From c105547501016897194358b11451608a8d5f9a02 Mon Sep 17 00:00:00 2001 From: Alexei Starovoitov Date: Wed, 28 Mar 2018 12:05:32 -0700 Subject: treewide: remove large struct-pass-by-value from tracepoint arguments - fix trace_hfi1_ctxt_info() to pass large struct by reference instead of by value - convert 'type array[]' tracepoint arguments into 'type *array', since compiler will warn that sizeof('type array[]') == sizeof('type *array') and later should be used instead The CAST_TO_U64 macro in the later patch will enforce that tracepoint arguments can only be integers, pointers, or less than 8 byte structures. Larger structures should be passed by reference.
