VLRU_Add_r() places a volume into VOL_STATE_VLRU_ADD before
calling VLRU_Wait_r(), which drops VOL_LOCK while waiting
for the required VLRU queue to quiesce. Thus, it is essential
that state VOL_STATE_VLRU_ADD be marked exclusive so that
another thread cannot mutate state until the VLRU generation
add transaction completes.

This patch adds support for backgrounding the page copies which are
caused by a call to readpages() In theory, this should improve the
throughput of the AFS kernel module as it permits processes to start
work whilst data is still being read into the page cache for later
pages.

The demand attach code defines volume pointers as volatile in
a number of places, despite the fact that the values in question

these volatile pointers into functions which don't treat them as
volatile (and even to some which assign them to registers).
This patch simply removes the use of volatile in this situation.

If cm_GetBuffer is being called in order to obtain a buffer to store

there is no reason to contact the file server. Instead use the cached

This logic avoids triggering the FetchData bug in all file servers

This patch adds a '--enable-checking' configuration option. When this
option is supplied, and gcc is in use, the compiler will treat any
warnings as errors. This will hopefully help stop new warnings from
creeping into the tree.
In order to still be able to build, all of the currently existing
warnings are accepted (these are documented in README.WARNINGS). With
this set of warning inhibitions, the tree is known to build on 32bit
Leopard - other systems may vary. Warning inhibition may be disabled
by supplying --enable-checking=all - in this case the tree will
definitely not build!
If --enabled-checking is not specified, the existing compilation
behaviour is maintained, so there is no user-visible change.
Gcc 4.2, or later, is required to use the pragma sets contained within
this patch. Again, they are not visible unless --enable-checking is
given.

In some situations, the fileserver returns a large negative number

cache manage to loop until RX aborts the connection.
This patch restores the old behaviour. length becomes a signed int once more
(and the original 32 bit length from the wire is used, rather than truncating
the 64 bit value), and the conditional checks for > 0.
