[PATCH 4.8 093/125] perf data: Fix building in 32 bit platform with libbabeltrace

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wang Nan <wangnan0@xxxxxxxxxx>

commit f2c8852e6e990fcab0d9e68de9d86e5fbea0b5dc upstream.

On ARM32 building it report following error when we build with
libbabeltrace:

  util/data-convert-bt.c: In function 'add_bpf_output_values':
  util/data-convert-bt.c:440:3: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Werror=format]
  cc1: all warnings being treated as errors

Fix it by changing %lu to %zu.
