Revision 23918b03060f6e572168fdde1798a905679d2e06 authored by Trond Myklebust on 20 November 2008, 21:06:21 UTC, committed by Linus Torvalds on 20 November 2008, 21:17:40 UTC
Fix a regression reported by Max Kellermann whereby kernel profiling showed that his clients were spending 45% of their time in rpcauth_lookup_credcache. It turns out that although his processes had identical uid/gid/groups, generic_match() was failing to detect this, because the task->group_info pointers were not shared. This again lead to the creation of a huge number of identical credentials at the RPC layer. The regression is fixed by comparing the contents of task->group_info if the actual pointers are not identical.
