[1] - recent patches to handle RPC read-ahead may involve small data
copy from header to data buffer, but surely not very high.
Amar - note that the current infrastructure present for 0-copy RDMA
might not be sufficient for GFAPI's 0-copy. A glfs_readv() request from
the app can come as a vector of memory pointers (and not a contiguous
iobuf) and therefore require storing an iovec/count as well. This might
also mean we need to exercise the scatter-gather aspects of the verbs API.
Got it.. Thats right.
Regards,
Amar
