Subject: [dpdk-dev] [PATCH v3 1/3] lib/lpm: integrate RCU QSBR
Date: Tue,  1 Oct 2019 13:28:55 -0500
Message-ID: <20191001182857.43867-2-honnappa.nagarahalli@arm.com> (raw)
In-Reply-To: <20191001182857.43867-1-honnappa.nagarahalli@arm.com>

From: Ruifeng Wang <ruifeng.wang@arm.com>

Currently, the tbl8 group is freed even though the readers might be
using the tbl8 group entries. The freed tbl8 group can be reallocated
quickly. This results in incorrect lookup results.

RCU QSBR process is integrated for safe tbl8 group reclaim.
Refer to RCU documentation to understand various aspects of
integrating RCU library into other libraries.
