Subject[PATCH net-next 0/1] rxrpc: Remove use of skbs from AFS [ver #2]
From
Date

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.

Changes:

(V2) Fixed afs_transfer_reply() whereby call->offset was incorrectly being
added to the buffer pointer (it doesn't matter as long as the reply
fits entirely inside a single packet).

Removed an unused goto-label and an unused variable.


The patch can be found here also:
