link_path_walk() currently treats the special filenames ".", ".."
and "/" differently in that it does not call down to the filesystem in
order to revalidate the cached dentry, but just assumes that it is
fine.

  For most filesystems this is OK, but it the case of the stateless
NFS, this means that it circumvents path staleness detection, and the
attribute+data cache revalidation code on such common commands as
opendir(".").

This change provides a way to do such revalidation for NFS without
impacting other filesystems. 

Note: the failure to revalidate the path here does not result in a
call to d_invalidate() unlike (all?) other calls to d_revalidate(). It
only results in an ESTALE error being returned to the caller.

Remove duplicate string definition. Same table already defined and
exported in irlan_event.c

Ircomm in 2.6.0-test3 can just set the owner field in the tty structure
like other drivers, and not mess with MOD_INC/MOD_DEC.

- set owner field on tty ldisc
- allocate network device objects with alloc_netdev
- use list_head macros and put locking around list of devices
- convert to seq_file for /proc
- use change_mtu hook rather than guessing at mtu changes

When doing the audit for this change, it was obvious that several drivers
allocate but never free the net_device.

This fixes these drivers.  This patch is riskier than the earlier
ones, because it isn't just a simple substitution and maybe there
is a reason they never free.

Drivers that use kfree in destructor are easily converted
to use free_netdev.

Replace kfree with free_netdev in cleanup routines
of protocols and network pseudo drivers.

s/kfree/free_netdev/ in cleanup routines of a bunch
of different network drivers.

Replace kfree with free_netdev

s/kfree/free_netdev/ as appropriate for tokenring drivers.

Simple one line substitution of kfree with free_netdev
for the bulk of the network drivers.

This patch adds the free_netdev function and associated
changes so that net_device structures are not freed until
last reference to the network device class is released.
