Subject: ipvs: Use min3() in ip_vs_dbg_callid()
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=9c37510b8ff2821ae4574858a6d4e83949c98a20;p=linux-edison.git

ipvs: Use min3() in ip_vs_dbg_callid()

There are two motivations for this:

1. It improves readability to my eyes
2. Using nested min() calls results in a shadowed _min1 variable,
   which is a bit untidy. Sparse complained about this.

I have also replaced (size_t)64 with a variable of type size_t and value 64.
This also improves readability to my eyes.
