Raw Blame History

From 9297af3ffd8a1c98f35fb7a273386576e061ff16 Mon Sep 17 00:00:00 2001

Subject: novfs: Add the Novell filesystem client kernel module
Patch-mainline: not yet, being worked on.
This adds the Novell filesystem client kernel module.
Things to do before it can be submitted:
- coding style cleanups
- remove typedefs
- function name lowercase
- 80 chars wide
- sparse cleanups
- __user markings
- endian markings
- remove functions that are never called and structures never used
- yeah, there are a lot of them...
- remove wrapper functions
- private kmalloc/free?
- resolve FIXME markings that have been added to the code
- wrong types passed to functions!!!
- userspace interface revisit
- uses /proc/novfs, not nice.
- might need userspace tools rework
- use of semaphore as mutex
- abuse of semaphore in lieu of completions.
Update May 13 2009 jeffm:
- Merged patches back into master novfs patch
