From: Gaetan Rivet Date: Mon, 23 Apr 2018 23:54:48 +0000 (+0200) Subject: devargs: make devargs list private X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c7b424c03d8ed4b050fc3455ac0a0c03c22f773e;p=dpdk.git devargs: make devargs list private Initially, rte_devargs was meant to be populated once and sometimes accessed, then never emptied. With the new hotplug functionality having better standing, new usage appeared with repeated addition of devices and their subsequent removal. Exposing devargs_list pushed bus drivers and libraries to be careless and inconsistent in their memory management. Making it private will allow to rationalize this part of the EAL and ensure that fewer memory leaks occur during operations.
