Subject: [PATCH net-next-2.6] [TIPC]: Enhancements to name table initialization
Date: Mon, 12 May 2008 16:33:03 -0400	[thread overview]
Message-ID: <1210624383-2175-1-git-send-email-allan.stephens@windriver.com> (raw)

This patch enhances the initialization of TIPC's name table
by removing a pointless spinlock operation, and by using
kcalloc() to detect requests for an oversized name table.
