From: Jason Xing <kernelxing@tencent.com>

The series is the product of previous review from sashiko[1].

1) META
patch 1: address TOCTOU around metadata.

2) PUBLISH of CQ
patch 2: make sure xsk_addr->addrs[] can be published to cq when
         overflow occurs.
patch 3: keep cleaning up the continuation descs (more than 17) and
         publish its address when overflow occurs.
patch 4: like patch 3, but only handles the invalid descs cases.
