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.
