How to enable debugging on NFS (dprintk)?

[Steve Fosdick]

There are some calls to dprintk within the NFS kernel code - how to I 
set things up to I can see the messages from these calls please?

It's controlled by /proc/sys/sunrpc/nfs_debug (or nfsd_debug for the 
server).

Not totally sure of the valid values, but it's an int bit field, so this 
will turn most things on (client side):

echo 65535 > /proc/sys/sunrpc/nfs_debug

See include/linux/sunrpc/debug.h, include/linux/nfs_fs.h (the very end,
where the NFSDBG_* macros are defined), and include/linux/nfsd/debug.h.
