sunrpc/cache: avoid variable over-loading in cache_defer_req

2009-09-18T21:01:12+00:00

In cache_defer_req, 'dreq' is used for two significantly different
values that happen to be of the same type.

This is both confusing, and makes it hard to extend the range of one of
the values as we will in the next patch.
So introduce 'discard' to take one of the values.

sunrpc/cache: use list_del_init for the list_head entries in cache_deferred_req

2009-09-18T15:47:49+00:00

Using list_del_init is generally safer than list_del, and it will
allow us, in a subsequent patch, to see if an entry has already been
processed or not.

sunrpc/cache: simplify cache_fresh_locked and cache_fresh_unlocked.

2009-09-11T21:08:54+00:00

The extra call to cache_revisit_request in cache_fresh_unlocked is not
needed, as should have been fairly clear at the time of
   commit 4013edea9a0b6cdcb1fdf5d4011e47e068fd6efb

If there are requests to be revisited, then we can be sure that
CACHE_PENDING is set, so the second call is sufficient.

So remove the first call.
Then remove the 'new' parameter,
then remove the return value for cache_fresh_locked which is only used
to provide the value for 'new'.

sunrpc/cache: change cache_defer_req to return -ve error, not boolean.

2009-09-11T21:03:27+00:00

As "cache_defer_req" does not sound like a predicate, having it return
a boolean value can be confusing.  It is more consistent to return
0 for success and negative for error.

Exactly what error code to return is not important as we don't
differentiate between reasons why the request wasn't deferred,
we only care about whether it was deferred or not.

SUNRPC: cache must take a reference to the cache detail's module on open()

2009-08-19T22:22:16+00:00

Otherwise we Oops if the module containing the cache detail is removed
before all cache readers have closed the file.

SUNRPC: Allow the cache_detail to specify alternative upcall mechanisms

2009-08-09T19:14:29+00:00

For events that are rare, such as referral DNS lookups, it makes limited
sense to have a daemon constantly listening for upcalls on a channel. An
alternative in those cases might simply be to run the app that fills the
cache using call_usermodehelper_exec() and friends.

The following patch allows the cache_detail to specify alternative upcall
mechanisms for these particular cases.
