Subject: SUNRPC: Use conventional switch statement when reclassifying sockets
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4232e8634ad82c5a53389e4016de15a8b15c09c3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

SUNRPC: Use conventional switch statement when reclassifying sockets

Clean up.

Defensive coding: If "family" is ever something that is neither
AF_INET nor AF_INET6, xs_reclassify_socket6() is not the appropriate
default action.  Choose to do nothing in that case.

Introduced by commit 6bc9638a.
