Subject: [ndctl PATCH v2 3/5] util/json: fix an error check for region resource
Date: Wed,  3 Oct 2018 12:15:04 -0600	[thread overview]
Message-ID: <20181003181506.17682-3-vishal.l.verma@intel.com> (raw)
In-Reply-To: <20181003181506.17682-1-vishal.l.verma@intel.com>

The return type of ndctl_region_get_resource() is 'unsigned long long',
and therefore the error checking for it should be done against
ULLONG_MAX. Fix an instance where we were checking against ULONG_MAX.
