From: Dennis Dalessandro <dennis.dalessandro@xxxxxxxxx> inline in trace functions causes the following build error when CONFIG_OPTIMIZE_INLINING is not defined in the kernel config: error: function can never be inlined because it uses variable argument lists Reported by 0-day build: https://lists.01.org/pipermail/kbuild-all/2015-August/011215.html This patch converts to a non-inline version of the hfi1 trace functions Reviewed-by: Jubin John <jubin.john@xxxxxxxxx> Reviewed-by: Mike Marciniszyn <mike.marciniszyn@xxxxxxxxx> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@xxxxxxxxx> --- drivers/staging/hfi1/trace.c | 15 +++++++++++- drivers/staging/hfi1/trace.h | 51 ++++++++++++++++-------------------------- 2 files changed, 32 insertions(+), 34 deletions(-) diff --git a/drivers/staging/hfi1/trace.c b/drivers/staging/hfi1/trace.c index afbb212..ea95591 100644 --- a/drivers/staging/hfi1/trace.c +++ b/drivers/staging/hfi1/trace.c @@ -48,7 +48,6 @@ * */ #define CREATE_TRACE_POINTS -#define HFI1_TRACE_DO_NOT_CREATE_INLINES #include "trace.h" u8 ibhdr_exhdr_len(struct hfi1_ib_header *hdr) @@ -208,4 +207,16 @@ const char *print_u64_array( return ret; } -#undef HFI1_TRACE_DO_NOT_CREATE_INLINES +__hfi1_trace_fn(PKT); +__hfi1_trace_fn(PROC); +__hfi1_trace_fn(SDMA); +__hfi1_trace_fn(LINKVERB); +__hfi1_trace_fn(DEBUG); +__hfi1_trace_fn(SNOOP); +__hfi1_trace_fn(CNTR); +__hfi1_trace_fn(PIO); +__hfi1_trace_fn(DC8051); +__hfi1_trace_fn(FIRMWARE); +__hfi1_trace_fn(RCVCTRL); +__hfi1_trace_fn(TID); + diff --git a/drivers/staging/hfi1/trace.h b/drivers/staging/hfi1/trace.h index 5c34606..05c7ce8 100644 --- a/drivers/staging/hfi1/trace.h +++ b/drivers/staging/hfi1/trace.h @@ -1339,22 +1339,17 @@ DECLARE_EVENT_CLASS(hfi1_trace_template, /* * It may be nice to macroize the __hfi1_trace but the va_* stuff requires an - * actual function to work and can not be in a macro.
