* io-threads: Cleanup request queueing,thread firingShehjar Tikoo2009-04-021-30/+38

* io-threads: Allow scaling to be switched offShehjar Tikoo2009-04-022-11/+73
| | | | | | | | The default is also to provide no scaling. For both, ordered and unordered request pools, when scaling is off, we maintain atleast the minimum number of threads specified in the volfile. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Add ordered threadpool state and codeShehjar Tikoo2009-04-022-58/+182
| | | | | | | | | | | Now we have the remaining fops going through the ordered thread-pool. To route a request through ordered thread, we use iot_schedule_ordered(..) and the worker thread for ordered requests is iot_worker_ordered(..) Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Add un-ordered thread-pool.Shehjar Tikoo2009-04-022-98/+334
| | | | | | | | | | | | | | | | | | This commit adds everything needed to: a. Get un-ordered request going through the un-ordered thread-pool. This happens through, the iot_schedule_unordered(..). The unordered thread-pool consists of thread running the iot_worker_unordered(..) function. b. Make threads in the un-ordered thread pool start-up and exit depending on the thread state. Note that at this point the requests that need ordering are still going through iot_schedule(..). Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Classify requests for threadpool typeShehjar Tikoo2009-04-021-26/+33
| | | | | | | | | | | | | | | | | New io-threads will serve requests through two separate threadpools. One thread pool for requests that must be ordered on a file that is open. so that the server can process the requests in the order they were entered in the requests queue, and not in the order the io-thread is able to send a request, which in turn is determined by how the thread gets scheduled. This can also be called the data-intensive ops thread pool. Second thread-pool for requests that dont care about ordering, i.e. requests like lookup, open, create, mkdir, etc. Signed-off-by: Anand V.

* unify-self-heal: Fix un-ref'ing of incorrect dictShehjar Tikoo2009-04-021-1/+1
| | | | | | | | | | | | | dict_unref'ing of the dict in local results in a crash due to de-referencing a NULL spinlock. That is because after a STACK_UNWIND(..), we cannot expect the frame->local to be allocated still. Fix by using the other available reference to local->dict.
