audit.56 merged with audit-2.6.git

[serue at us.ibm.com]

My ultra-superficial comments:

How about #defines for arguments to audit_update_watch?  0 and 1, not
meaningful.

struct watch_transport: member "valid" is unused??

char                    *w_filterkey;   /* An arbitrary filtering key */
s/arbitrary/meaningful/ ?

You have lines ending in a space
You have lines with spaces for tabs

Now looking at locking.  I assume that you feel confident enough at
this point about the placement of the update_watch'es and that you
are catching all meaningful fs events?
