This series completes the conversion of Documentation/filesystems/nfs to ReST.

Note that I chose csv-table over list-table because csv files are easier
to export from other software. 

I did not think these rst files were supposed to be
in admin-guide, so I left them where they are.

Convert nfs41-server.txt to ReST. The ASCII tables were converted to
csv-tables and not list-tables because the former is easier to export
from spreadsheets.

+=============================
+NFSv4.1 Server Implementation
+=============================
+
+Server support for minorversion 1 can be controlled using the
+/proc/fs/nfsd/versions control file.  The string output returned
+by reading this file will contain either "+4.1" or "-4.1"
+correspondingly.
+
+Currently, server support for minorversion 1 is enabled by default.
+It can be disabled at run time by writing the string "-4.1" to
+the /proc/fs/nfsd/versions control file.  Note that to write this
+control file, the nfsd service must be taken down.  You can use rpc.nfsd
+for this; see rpc.nfsd(8).
+
+(Warning: older servers will interpret "+4.1" and "-4.1" as "+4" and
+"-4", respectively.  Therefore, code meant to work on both new and old
+kernels must turn 4.1 on or off *before* turning support for version 4
+on or off; rpc.nfsd does this correctly.)
+
+The NFSv4 minorversion 1 (NFSv4.1) implementation in nfsd is based
+on RFC 5661.
+
+From the many new features in NFSv4.1 the current implementation
+focuses on the mandatory-to-implement NFSv4.1 Sessions, providing
+"exactly once" semantics and better control and throttling of the
+resources allocated for each client.
+
+The table below, taken from the NFSv4.1 document, lists
+the operations that are mandatory to implement (REQ), optional
+(OPT), and NFSv4.0 operations that are required not to implement (MNI)
+in minor version 1.  The first column indicates the operations that
+are not supported yet by the linux server implementation.
+
+The OPTIONAL features identified and their abbreviations are as follows:
+
+- **pNFS**	Parallel NFS
+- **FDELG**	File Delegations
+- **DDELG**	Directory Delegations
+
+The following abbreviations indicate the linux server implementation status.
+
+- **I**	Implemented NFSv4.1 operations.
+- **NS**	Not Supported.
+- **NS\***	Unimplemented optional feature.

+
+Implementation notes:
+=====================
+
+SSV:
+  The spec claims this is mandatory, but we don't actually know of any
+  implementations, so we're ignoring it for now.  The server returns
+  NFS4ERR_ENCR_ALG_UNSUPP on EXCHANGE_ID, which should be future-proof.
+
+GSS on the backchannel:
+  Again, theoretically required but not widely implemented (in
+  particular, the current Linux client doesn't request it).  We return
+  NFS4ERR_ENCR_ALG_UNSUPP on CREATE_SESSION.
+
+DELEGPURGE:
+  mandatory only for servers that support CLAIM_DELEGATE_PREV and/or
+  CLAIM_DELEG_PREV_FH (which allows clients to keep delegations that
+  persist across client reboots).  Thus we need not implement this for
+  now.
+
+EXCHANGE_ID:
+  implementation ids are ignored
+
+CREATE_SESSION:
+  backchannel attributes are ignored
+
+SEQUENCE:
+  no support for dynamic slot table renegotiation (optional)
+
+Nonstandard compound limitations:
+  No support for a sessions fore channel RPC compound that requires both a
+  ca_maxrequestsize request and a ca_maxresponsesize reply, so we may
+  fail to live up to the promise we made in CREATE_SESSION fore channel
+  negotiation.

-Implementation notes:
-
-SSV:
-* The spec claims this is mandatory, but we don't actually know of any
-  implementations, so we're ignoring it for now.  The server returns
-  NFS4ERR_ENCR_ALG_UNSUPP on EXCHANGE_ID, which should be future-proof.
-
-GSS on the backchannel:
-* Again, theoretically required but not widely implemented (in
-  particular, the current Linux client doesn't request it).  We return
-  NFS4ERR_ENCR_ALG_UNSUPP on CREATE_SESSION.
-
-DELEGPURGE:
-* mandatory only for servers that support CLAIM_DELEGATE_PREV and/or
-  CLAIM_DELEG_PREV_FH (which allows clients to keep delegations that
-  persist across client reboots).  Thus we need not implement this for
-  now.
-
-EXCHANGE_ID:
-* implementation ids are ignored
-
-CREATE_SESSION:
-* backchannel attributes are ignored
-
-SEQUENCE:
-* no support for dynamic slot table renegotiation (optional)
-
-Nonstandard compound limitations:
-* No support for a sessions fore channel RPC compound that requires both a
-  ca_maxrequestsize request and a ca_maxresponsesize reply, so we may
-  fail to live up to the promise we made in CREATE_SESSION fore channel
-  negotiation.

Convert knfsd-stats.txt to ReST. Content remains mostly the same.

OK, I've made a quick pass through these.  They are mostly OK, with a
couple of exceptions.  One is that it has the "#." problem in enumerated
lists, which needs to be fixed as was done with the previous set.

And then there is:

That leads to results that look like this:

...and that is essentially unreadable.  Remember that the plain-text
format matters too, so we can't do it this way.

The original is in something fairly close to the RST multicell table
format already; it shouldn't be too hard to add the tweaks needed to make
sphinx happy...?

Thanks,
