AFS documentation

AFS documentation

[Randy Dunlap]

Hi David,

I was browsing Documentation/filesystems/afs.rst and fs/afs/super.c
and had a few questions/comments.

1.  afs.rst says:

<<<
When inserting the driver modules the root cell must be specified along with a
list of volume location server IP addresses::

	modprobe rxrpc
	modprobe kafs rootcell=cambridge.redhat.com:172.16.18.73:172.16.18.91

The first module is the AF_RXRPC network protocol driver.  This provides the
RxRPC remote operation protocol and may also be accessed from userspace.  See:

	Documentation/networking/rxrpc.rst

The second module is the kerberos RxRPC security driver, and the third module
is the actual filesystem driver for the AFS filesystem.
>>>

so that above mentions 3 modules but only lists (modprobes) 2 of them.
Or am I missing something?


2.  fs/afs/super.c seems to be willing to parse "source=" (Opt_source).

Can you tell me the format & meaning of that mount option?
and maybe even add it to the doc. file?



thanks.

Ah, I see that source= is a general fs mount option.  Never mind on that one.  :)
