Subject: [dpdk-stable] [PATCH 2/4] app/procinfo: fix negative check on unsigned variable
Date: Tue, 17 Nov 2020 17:14:33 +0000
Message-ID: <20201117171435.2303641-3-ferruh.yigit@intel.com> (raw)
In-Reply-To: <20201117171435.2303641-1-ferruh.yigit@intel.com>

'parse_xstats_ids()' return 'int'. The return value is assigned to
'nb_xstats_ids' unsigned value, later negative check on this variable is
wrong.

Adding interim 'int' variable for negative check.

Fixes: 7ac16a3660c0 ("app/proc-info: support xstats by ID and by name")
Cc: stable@dpdk.org
