Subject: [INET_DIAG]: Introduce sk_diag_fill
X-Git-Tag: tegra-9.12.3~24590^2
X-Git-Url: https://nv-tegra.nvidia.com/r/gitweb?p=linux-2.6.git;a=commitdiff_plain;h=dff2c03534f525813342ab8dec90c5bb1ee07471;hp=-c

[INET_DIAG]: Introduce sk_diag_fill

To be called from inet_diag_get_exact, also rename inet_diag_fill to
inet_csk_diag_fill, for consistency with inet_twsk_diag_fill.
