* | param: use ops in struct kernel_param, rather than get and set fns directlyRusty Russell2010-08-111-11/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.

| * sunrpc: make the cache cleaner workqueue deferrableArtem Bityutskiy2010-07-062-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the cache_cleaner workqueue deferrable, to prevent unnecessary system wake-ups, which is very important for embedded battery-powered devices. do_cache_clean() is called every 30 seconds at the moment, and often makes the system wake up from its power-save sleep state. With this change, when the workqueue uses a deferrable timer, the do_cache_clean() invocation will be delayed and combined with the closest "real" wake-up. This improves the power consumption situation. Note, I tried to create a DECLARE_DELAYED_WORK_DEFERRABLE() helper macro, similar to DECLARE_DELAYED_WORK(), but failed because of the way the timer wheel core stores the deferrable flag (it is the LSBit in the time->base pointer). My attempt to define a static variable with this bit set ended up with the "initializer element is not constant" error. Thus, I have to use run-time initialization, so I created a new cache_initialize() function which is called once when sunrpc is being initialized.

This call is currently made in each ->xpo_recvfrom function, often from multiple different points. In each case it is the earliest point on a particular path where it is known that the protection provided by XPT_BUSY is no longer needed. However there are (still) some error paths which do not call svc_xprt_received, and requiring each ->xpo_recvfrom to make the call does not encourage robustness. So: move the svc_xprt_received call to be made just after the call to ->xpo_recvfrom(), and move it of the various ->xpo_recvfrom methods. This means that it may not be called at the earliest possible instant, but this is unlikely to be a measurable performance issue. Note that there are still other calls to svc_xprt_received as it is also needed when an xprt is newly created. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.

This ensures that we only ever get a usable entry, or an entry that will become usable once an update arrives. i.e. we will never need to repeat the lookup. This allows us to remove the 'is_expired' test from cache_check (i.e. from cache_is_valid). cache_check should never get an expired entry as 'lookup' will never return one. If it does happen - due to inconvenient timing - then just accept it as still valid, it won't be very much past it's use-by date. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.

This was needed long ago when the auth_domain cache used the same cache infrastructure. But since that (being a very different sort of cache) was separated, this test is no longer needed. So remove the test on refcnt and tidy up the surrounding code. This allows the cache_dequeue call (which needed to be there to drop a potentially awkward reference) can be moved outside of the spinlock which is a better place for it.
