2016-09-27sunrpc: queue work on system_power_efficient_wqKe Wang
sunrpc uses workqueue to clean cache regulary. There is no real dependency of executing work on the cpu which queueing it. On a idle system, especially for a heterogeneous systems like big.LITTLE, it is observed that the big idle cpu was woke up many times just to service this work, which against the principle of power saving. It would be better if we can schedule it on a cpu which the scheduler believes to be the most appropriate one. After apply this patch, system_wq will be replaced by system_power_efficient_wq for sunrpc. This functionality is enabled when CONFIG_WQ_POWER_EFFICIENT is selected.

2016-09-23NFS: direct: use complete() instead of complete_all()Daniel Wagner
There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). nfs_file_direct_write() or nfs_file_direct_read() allocated a request object via nfs_direct_req_alloc(), which initializes the completion. The request object then is freed later in the exit path. Between the initialization and the release either nfs_direct_write_schedule_iovec() resp nfs_direct_read_schedule_iovec() are called which will asynchronously process the request. The calling function waits via nfs_direct_wait() till the async work has been done. Thus there is only one waiter on the completion. nfs_direct_pgio_init() and nfs_direct_read_completion() are passed via function pointers to nfs pageio. The first function does a ref counting (get_dreq() and put_dreq()) which ensures that nfs_direct_read_completion() and nfs_direct_read_schedule_iovec() only call the completion path once. The usage pattern of the completion is: waiter context waker context nfs_file_direct_write() dreq = nfs_direct_req_alloc() init_completion() nfs_direct_write_schedule_iovec() nfs_direct_wait() wait_for_completion_killable() nfs_direct_write_schedule_work() nfs_direct_complete() complete() nfs_file_direct_read() dreq = nfs_direct_req_all() init_completion() nfs_direct_read_schedule_iovec() nfs_direct_wait() wait_for_completion_killable() nfs_direct_read_schedule_iovec() nfs_direct_complete() complete() nfs_direct_read_completion() nfs_direct_complete() complete() Signed-off-by: Daniel Wagner <daniel.wagner@bmw-carit.de> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

2016-09-22nfs: allow blocking locks to be awoken by lock callbacksJeff Layton
Add a waitqueue head to the client structure. Have clients set a wait on that queue prior to requesting a lock from the server. If the lock is blocked, then we can use that to wait for wakeups. Note that we do need to do this "manually" since we need to set the wait on the waitqueue prior to requesting the lock, but requesting a lock can involve activities that can block. However, only do that for NFSv4.1 locks, either by compiling out all of the waitqueue handling when CONFIG_NFS_V4_1 is disabled, or skipping all of it at runtime if we're dealing with v4.0, or v4.1 servers that don't send lock callbacks. Note too that even when we expect to get a lock callback, RFC5661 section 20.11.4 is pretty clear that we still need to poll for them, so we do still sleep on a timeout. We do however always poll at the longest interval in that case.
