Message-ID: <20070411191002.15499.54512.stgit@warthog.cambridge.redhat.com>
Date: Wed, 11 Apr 2007 20:10:02 +0100

Subject: [PATCH 1/8] AF_RXRPC: Use own workqueues
Make the AF_RXRPC module use its own workqueues with their own per-CPU threads.
Currently it uses keventd to do the following tasks, amongst others:
(*) Security negotiation
(*) Packet encryption and decryption
(*) Packet resending
(*) ACK, abort and busy packet generation
(*) Timeout handling
(*) Missing packet catchup
(*) Parts of incoming call management
(*) Destruction of structures we've finished with
Some of these conflict with AFS's use of keventd, however, and can lead to
effective deadlock of resources. Having discussed this, it has been suggested
that encryption and decryption shouldn't be done in keventd (that's not
unreasonable - it is potentially quite slow), and so the AF_RXRPC service is
given its own threads rather than AFS.
It might be useful to consider using the rpciod threads for this, if they were
separated out from the SunRPC module.
