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?
