[PATCH 00/17] staging: remove requirement that lustre be built as module

[NeilBrown]

The main focus on this series is to remove the requirement that
lustre be built as a module.  The involves moving some initialization
out of the module_init functions and putting it elsewhere.

This lead me to look at various kthreads that are used, resulting is
some of them being changed to simpler work-queues.

Lustre has a 'struct ptlrpc_thread' data structure which appears to
have been created to manage the multiple threads for ptlrpcd - and it
does this quite effectively.
It was also used for managing a few other threads, and it was much
less suitable for these.  Those which haven't been changed to
workqueues have been changed to use kthread interfaces directly.

There are also a few bug-fixes and minor clean-ups.

This series doesn't introduce any new failures in the 'sanity' test
suite.

Thanks,
NeilBrown
