From e7e769b409eb9239d128c29a60fcaa76506cd5b1 Mon Sep 17 00:00:00 2001 From: Wei Dai Date: Wed, 27 Jul 2016 19:25:56 +0800 Subject: [PATCH] eal: fix tail blank check in --lcores argument the tail blank after a group of lcore or cpu set will make check of its end character fail. for example: --lcores '(0-3)@(0-3) ,(4-5)@(4-5)', the next character after cpu set (0-3) is not ',' or '\0', which fail the check in eal_parse_lcores( ).
