[Cluster-devel] [PATCH dlm/next 0/6] fs: dlm: rework receive and transmit handling

[Alexander Aring <aahringo@redhat.com>]

Hi,

This patch series contains a huge change regarding to the
receive/transmit handling of dlm. As I placed sequence numbering on dlm
messages I expierenced that dlm messages can be transmitted in an
incorrect order. I changed the transmit handling that the writequeue
handles entries per dlm message buffer and sendmsg() will use
scatter/gather to transmit a bunch of them. At the receive handling I
removed some allocations and copies into different buffers. There is
only one receive buffer now which fill be get filled and the upper layer
will working on that buffer as well.
