SUNRPC: Fix a performance regression in the RPC authentication code
...
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.
