[PATCH 3.4 55/88] nfsd: pass net to nfsd_startup() and nfsd_shutdown()

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislav Kinsbursky <skinsbursky@xxxxxxxxxxxxx>

commit db42d1a76a8dfcaba7a2dc9c591fa4e231db22b3 upstream.

Precursor patch. Hard-coded "init_net" will be replaced by proper one in
future.

[wengmeiling: backport to 3.4:
 - adjust context
 - one more parameter(int port) for nfsd_startup()
 - no net ns initialization in nfsd_shutdown()
 - pass @net to lockd_up() in nfsd_startup()
 - pass @net to lockd_down() in nfsd_shutdown()]
