Subject: [libnftnl PATCH v2 2/9] include: add new bitwise bit-length attribute to nf_tables.h
Date: Mon, 4 Apr 2022 13:06:16 +0100 [thread overview]
Message-ID: <20220404120623.188439-3-jeremy@azazel.net> (raw)
In-Reply-To: <20220404120623.188439-1-jeremy@azazel.net>
The kernel can now keep track of the bit-length of boolean expressions.
