know.  This was a no-op, now it's a silent no-op.

*   Fixed help string in lctl.

*   Fixed lctl set_route date+time parsing bug.

*  Fixed missing kfree in the router

*  Converted some socknal and router CERRORs into CWARN/CDEBUGs

  routers (i.e. gateways) without forgetting network topology
  (i.e. adding/deleting routes).

* Socknal and qswnal automatically notify their local router and make an
  upcall when they detect peer death.

* portals router load balances over equivalent routes

* ENETUNREACH returned when a NAL thinks the router isn't loaded.

* Improved socknal network failure detection.

* /proc/sys/socknal/* interface

  - timeout is the socknal I/O timeout (50 by default) in seconds .

  - eager_ack is a boolean (set by default) that enables setting
    TCP_QUICKACK after every incoming message to ensure peer zero-copy
    sends complete quickly.

  - zero_copy is the size (2k by default) in bytes, below which message
    fragments are copied into a socket, rather than using zero-copy sends.
    Setting this above PAGE_SIZE will disable zero copy.

* Socknal autoconnect option to create all peer connections eagerly or not.
  If more than one autoconnect reaches the same peer NID, with the eager
  option (this was the previous default), all connections will be made when
  one is required, otherwise only one at a time will be attempted (the new
  default).  NB socknal still load balances over all established
  connections.

* Generalised portals upcall to "cmd <action> [params]".  Current upcalls
  are...

  - upcall LBUG file fn line

  - upcall ROUTER_NOTIFY <nal> <nid> <timestamp> up|down
    where <nal> is the kernel NAL number (defined in <linux/kp30.h>)
          <nid> is the peer's NID in 0xhex
          <timestamp> is seconds since 1/1/1970

* Added 'lctl --net' option, to make 1-line network lctl commands easy.

* Added Light-weight event tracing.

We don't need to re-check the atime/mtime set flags in fsfilt_ext3_setattr,
we do it already in mds_fix_attr().

backport completion_ast fixes and lustre_dlm.h header updates from b_devel

More debug, less noise, in ldlm_lock_dump

have cascading failures.  Server bulk timeout is 1/4 of the client timeout.
Also fix /proc variables to be int, as that is what the functions expect.

Originally for bug 1684, later found to be caused by stack overflows.

Was apparently fixed in the client and development branches, but not HEAD.

Fixes LBUG in ll_it_open_error, if the server couldn't lookup the parent.

don't do the del_autconn for non-tcp interfaces.

backport from b_devel to HEAD this patch to avoid an assertion in an
unlikely error case where the server is unable to even begin to
process an intent request

This patch from eeb tracks outstanding tx descriptors and provides an
ioctl to fetch them; should be useful for tracking down cases where
bug 1031 is not resolved by loading the modules (see also bug 1827)

bumped the kernel patch version to 23, but really only vanilla-2.4.20 changed
