Subject: lockd: rename lockd_create_svc() to lockd_get()
X-Git-Tag: v5.17-rc1~75^2~34
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ecd3ad68d2c6d3ae178a63a2d9a02c392904fd36;p=thirdparty%2Fkernel%2Flinux.git

lockd: rename lockd_create_svc() to lockd_get()

lockd_create_svc() already does an svc_get() if the service already
exists, so it is more like a "get" than a "create".

So:
 - Move the increment of nlmsvc_users into the function as well
 - rename to lockd_get().

It is now the inverse of lockd_put().
