Subject: NFSv4: Deal with some more sparse warnings
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=17f26b1246425a5b77f05ac871889265357566a8;p=linux-beck.git

NFSv4: Deal with some more sparse warnings

Technically, we don't really need to convert these time stamps,
since they are actually cookies.
