Subject: [PATCH v2 3/3] flowcache: more "unsigned int"
Date: Mon, 3 Apr 2017 00:53:15 +0300 [thread overview]
Message-ID: <20170402215315.GC8938@avx2> (raw)
In-Reply-To: <20170402215150.GA8938@avx2>
Make ->hash_count, ->low_watermark and ->high_watermark unsigned int
and propagate unsignedness to other variables.
This change doesn't change code generation because these fields aren't
used in 64-bit contexts but make it anyway: these fields can't be
negative numbers.
