Implement the new swapfile a_ops for NFS and hook up ->direct_IO. This will set the NFS socket to SOCK_MEMALLOC and run socket reconnect under PF_MEMALLOC as well as reset SOCK_MEMALLOC before engaging the protocol ->connect() method. PF_MEMALLOC should allow the allocation of struct socket and related objects and the early (re)setting of SOCK_MEMALLOC should allow us to receive the packets required for the TCP connection buildup.

This option allows the NFS client and server to support

an RDMA-enabled transport.

To compile RPC client RDMA transport support as a module,

choose M here: the module will be called xprtrdma.

Choose Y here to enable Secure RPC using the Kerberos version 5
|
|
GSS-API mechanism (RFC 1964).
|
|
|
|
Secure RPC calls with Kerberos require an auxiliary user-space
|
|
daemon which may be found in the Linux nfs-utils package
|
|
available from http://linux-nfs.org/. In addition, user-space
|
|
Kerberos support should be installed.

help
|

This option enables a sysctl-based debugging interface
|
|
that is be used by the 'rpcdebug' utility to turn on or off
|
|
logging of different aspects of the kernel RPC activity.
|
|
|
|
Disabling this option will make your kernel slightly smaller,
|
|
but makes troubleshooting NFS issues significantly harder.

|
|
If unsure, say Y.
