Subject: [PATCH net-next] rxrpc: Remove use of skbs from AFS
Date: Tue, 30 Aug 2016 16:52:32 +0100 [thread overview]
Message-ID: <147257235268.6716.12062621584578937716.stgit@warthog.procyon.org.uk> (raw)
Here's a single patch that removes the use of sk_buffs from fs/afs. From
this point on they'll be entirely retained within net/rxrpc and AFS just
asks AF_RXRPC for linear buffers of data. This needs to be applied on top
of the just-posted preparatory patch set.
This makes some future developments easier/possible:
(1) Simpler rxrpc_call usage counting.
(2) Earlier freeing of metadata sk_buffs.
(3) Rx phase shortcutting on abort/error.
(4) Encryption/decryption in the AFS fs contexts/threads and directly
between sk_buffs and AFS buffers.
(5) Synchronous waiting in reception for AFS.
The patch can be found here also:
