rpc-transport: don't merge payload iobuf and iobuf which holds program header into single iobref.

2010-11-25T08:34:09+00:00

- io-cache holds a reference on iobref passed from transport layer. Hence,
   two iobufs are accounted instead of one in calculated used cache size.

rpc-transport/rdma: set the default quota of recv buffers to 128.

2010-11-09T10:12:11+00:00

- since quota is returned once the reply is recieved, 32 is too less value.

rpc-transport/rdma: Fix 2KB as threshold size for msgs that can be transferred inline.

2010-11-08T04:15:08+00:00

- Any fop/mop that can result a reply whose size is greater than this threshold
    allocates and submits a buffer along with the request to receive reply.

rpc-transport/rdma: increment post->ctx.count in a loop doint rdma_read.

2010-11-08T04:15:02+00:00

- incrementing by the number of read chunks even before doing rdma read will
    cause issues since post->ctx.count is used while posting rdma read.

BUG: 1877 (data corruption while running arequal.)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1877

rpc-transport: fix race-condition between rdma-read completion and updating the count of number of vectors to be passed to rpc.

2010-10-29T10:42:22+00:00

- If rdma read completes before incrementing the vector count, the count
    value sent to rpc will be improper. For fops like write, this may result
    in missing out a vector to be written, thereby causing data corruption.
