Put lkb_astparam in a union with a dlm_user_args pointer to
eliminate a lot of type casting.

dlm: proper types for asts and basts2008-02-06T06:35:45ZDavid Teigland2008-02-06T06:35:45Zurn:sha1:e5dae548b0b5397e070de793be925cfc5813ad95
Use proper types for ast and bast functions, and use
consistent type for ast param.

dlm: make find_rsb() fail gracefully when namelen is too large2008-02-04T07:26:31ZAl Viro2008-01-26T04:22:26Zurn:sha1:ef58bccab7c7ef34451aa4ceea39545ef126b666
We *can* get there from receive_request() and dlm_recover_master_copy()
with namelen too large if incoming request is invalid; BUG() from
DLM_ASSERT() in allocate_rsb() is a bit excessive reaction to that
and in case of dlm_recover_master_copy() we would actually oops before
that while calculating hash of up to 64Kb worth of data - with data
actually being 64 _bytes_ in kmalloc()'ed struct.

* check that length is large enough to cover the non-variable part of message or
rcom resp. (after checking that it's large enough to cover the header, of
course).
* kill more pointless casts

dlm: use proper C for dlm/requestqueue stuff (and fix alignment bug)2008-02-04T07:21:32ZAl Viro2008-01-25T05:28:28Zurn:sha1:8b0d8e03f847d9c1677b8a193cd124debbc54633
a) don't cast the pointer to dlm_header *, we use it as dlm_message *
anyway.
b) we copy the message into a queue element, then pass the pointer to
copy to dlm_receive_message_saved(); declare it properly to make sure
that we have the right alignment.

dlm: keep cached master rsbs during recovery2008-01-30T17:04:43ZDavid Teigland2008-01-16T19:02:31Zurn:sha1:85f0379aa0f9366bb6918e2e898a915231176fbd
To prevent the master of an rsb from changing rapidly, an unused rsb is kept
on the "toss list" for a period of time to be reused. The toss list was
being cleared completely for each recovery, which is unnecessary. Much of
the benefit of the toss list can be maintained if nodes keep rsb's in their
toss list that they are the master of. These rsb's need to be included
when the resource directory is rebuilt during recovery.
