From: Chuck Lever Date: Mon, 6 Aug 2007 15:57:02 +0000 (-0400) Subject: SUNRPC: Add hex-formatted address support to rpc_peeraddr2str() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fbfe3cc677c1a62ca6472abf24d03d4bf9f03a55;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git SUNRPC: Add hex-formatted address support to rpc_peeraddr2str() Add support for the NFS client's need to export volume information with IP addresses formatted in hex instead of decimal. This isn't used yet, but subsequent patches (not in this series) will change the NFS client to use this functionality.
