The patch titled
Spidernet: cleanup un-needed API
has been removed from the -mm tree. Its filename was
spidernet-cleanup-un-needed-api.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Spidernet: cleanup un-needed API
From: Linas Vepstas <linas@xxxxxxxxxxxxxx>
There is no need to pass a flag into spider_net_decode_one_descr() so remove
this, and perform some othre minor cleanup.
