Subject: lib/procfs: return uint64_t from procfs_process_get_stat_nth()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=34625df4ee63fdc5c851902c94e13b56bcdef6cb;p=thirdparty%2Futil-linux.git

lib/procfs: return uint64_t from procfs_process_get_stat_nth()

This functions uses ul_strtoul64() to parse the number. As indicated by
the name that can only handle uint64_t values. Passing it a pointer to
uintmax_t can produce a compiler warning.
