Subject: RDMA/core: Avoid exporting module local functions and remove not-used ones
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d466b155f83890f2f2d4cf6d0f623ac2d455b12;p=thirdparty%2Fkernel%2Flinux.git

RDMA/core: Avoid exporting module local functions and remove not-used ones

Some of the functions are local to the module and some are not used
starting from commit 36783dec8d79 ("RDMA/rxe: Delete deprecated module
parameters interface"). Delete and avoid exporting them.
