docs: filesystems: convert coda.txt to ReST
This document has its own style. It seems to be print output
for the old matrixial printers where backspace were used to
do double prints.
For the conversion, I used several regex expressions to get
rid of some weird stuff. The patch also does almost all possible
conversions in order to get a nice output document, while keeping
it readable/editable as is:
- Add a SPDX header;
- Add a document title;
- Adjust document title;
- Adjust section titles;
- Some whitespace fixes and new line breaks;
- Mark literal blocks as such;
- Adjust list markups;
- Mark some unumbered titles with bold font;
- Use footnoote markups;
- Add table markups;
- Use notes markups;
- Add it to filesystems/index.rst.

It should now be like this:

The Sphinx build system for PDF is too complex and generate
lots of ancillary files, including one PDF file for each

confusing and it makes harder to identify when something didn't

scripts: kernel-doc: proper handle @foo->bar()
The pattern @foo->bar() is valid, as it can be used by a
function pointer inside a struct passed as a parameter.
Right now, it causes a warning:
./drivers/firewire/core-transaction.c:606: WARNING: Inline strong start-string without end-string.
In this specific case, the kernel-doc markup is:
/**
* fw_core_remove_address_handler() - unregister an address handler
* @handler: callback
*
* To be called in process context.
*
* When fw_core_remove_address_handler() returns, @handler->callback() is
* guaranteed to not run on any CPU anymore.
*/
With seems valid on my eyes. So, instead of trying to hack
the kernel-doc markup, let's teach it about how to handle
such things. This should likely remove lots of other similar
warnings as well.

argument. For instance:
long work_on_cpu(int cpu, long (*fn) (void *, void * arg)

"void *" of the 'fn' arguments from the ", void * arg" which
is an argument to work_on_cpu().

x86/split_lock: Provide handle_guest_split_lock()
Without at least minimal handling for split lock detection induced #AC,
VMX will just run into the same problem as the VMWare hypervisor, which
was reported by Kenneth.
It will inject the #AC blindly into the guest whether the guest is
prepared or not.
Provide a function for guest mode which acts depending on the host
SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a
warning, disable SLD and mark the task accordingly. Otherwise force
SIGBUS.
[ bp: Add a !CPU_SUP_INTEL stub for handle_guest_split_lock(). ]

"A fix and two cleanups.
Fix:
- Christoph Hellwig noticed that some logic I added to
orangefs_file_read_iter introduced a race condition, so he sent a
reversion patch. I had to modify his patch since reverting at this
point broke Orangefs.
Cleanups:
- Christoph Hellwig noticed that we were doing some unnecessary work
in orangefs_flush, so he sent in a patch that removed the un-needed
code.
- Al Viro told me he had trouble building Orangefs. Orangefs should
be easy to build, even for Al :-).
I looked back at the test server build notes in orangefs.txt, just
in case that's where the trouble really is, and found a couple of
typos and made a couple of clarifications"
