SUNRPC: Use TCP_CORK to optimise send performance on the server

2021-02-16T17:32:31Z

Use a counter to keep track of how many requests are queued behind the xprt->xpt_mutex, and keep TCP_CORK set until the queue is empty. Signed-off-by: Trond Myklebust Link: https://lore.kernel.org/linux-nfs/20210213202532.23146-1-trondmy@kernel.org/T/#u Signed-off-by: Chuck Lever

SUNRPC: Move simple_get_bytes and simple_get_netobj into private header

2021-01-25T20:59:12Z

Remove duplicated helper functions to parse opaque XDR objects and place inside new file net/sunrpc/auth_gss/auth_gss_internal.h. In the new file carry the license and copyright from the source file net/sunrpc/auth_gss/auth_gss.c. Finally, update the comment inside include/linux/sunrpc/xdr.h since lockd is not the only user of struct xdr_netobj. Signed-off-by: Dave Wysochanski Signed-off-by: Trond Myklebust

svcrdma: Reduce Receive doorbell rate

2021-01-25T14:36:28Z

This is similar to commit e340c2d6ef2a ("xprtrdma: Reduce the doorbell rate (Receive)") which added Receive batching to the client. Signed-off-by: Chuck Lever

svcrdma: Deprecate stat variables that are no longer used

2021-01-25T14:36:28Z

Clean up. We are not permitted to remove old proc files. Instead, convert these variables to stubs that are only ever allowed to display a value of zero. Signed-off-by: Chuck Lever

svcrdma: Restore read and write stats

2021-01-25T14:36:28Z

Now that we have an efficient mechanism to update these two stats, let's start maintaining them again. Signed-off-by: Chuck Lever

svcrdma: Convert rdma_stat_sq_starve to a per-CPU counter

2021-01-25T14:36:28Z

Avoid the overhead of a memory bus lock cycle for counting a value that is hardly every used. Signed-off-by: Chuck Lever

svcrdma: Convert rdma_stat_recv to a per-CPU counter

2021-01-25T14:36:28Z

Receives are frequent events. Avoid the overhead of a memory bus lock cycle for counting a value that is hardly every used. Signed-off-by: Chuck Lever

SUNRPC: Move definition of XDR_UNIT

2021-01-25T14:36:23Z

Clean up: The unit of XDR alignment is defined by RFC 4506, not as part of the RPC message header. Thus it belongs in include/linux/sunrpc/xdr.h. Signed-off-by: Chuck Lever
