From e45bb02174812e4935214f42a18725be320770d5 Mon Sep 17 00:00:00 2001
From: Chen Qi <Qi.Chen@windriver.com>

Subject: [PATCH 10/26] Use uintmax_t for handling rlim_t
PRIu{32,64} is not right format to represent rlim_t type
therefore use %ju and typecast the rlim_t variables to
uintmax_t.
Fixes portablility errors like
execute.c:3446:36: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'rlim_t {aka long long unsigned int}' [-Werror=format=]
| fprintf(f, "%s%s: " RLIM_FMT "\n",
| ^~~~~~~~
| prefix, rlimit_to_string(i), c->rlimit[i]->rlim_max);
