Subject: mempool/cnxk: avoid batch op free for empty pools
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7c754f553e500557f322958647281d541899ed14;p=dpdk.git

mempool/cnxk: avoid batch op free for empty pools

Batch op data is initialized inside mempool alloc. But
in case of empty mempools, the alloc function is not
called and hence the initialization of batch op data is
also not done. So ensure the validity of batch op data
inside mempool free.
