NFS Mount Option 'nofsc'

[Derek McEachern <derekm@xxxxxx>]

I joined the mailing list shortly after Neil sent out a request for 
volunteer to update the nfs man page documenting the 'fsc'/'nofsc' 
options. I suspect this may stem from a ticket we opened with Suse 
inquiring about these options.

Coming from a Solaris background we typically use the 'forcedirectio' 
option for certain mounts and I was looking for the same thing in Linux. 
The typically advice seems to be use 'noac' but the description in the 
man page doesn't seem to match what I would expect from 'forcedirectio', 
namely no buffering on the client.

Poking around the kernel I found the 'fsc'/'nofsc' options and my 
question is does 'nofsc' provide 'forcedirectio' functionality?

Thanks,
Derek
