NFSv4: Fix callback server shutdown

2017-09-27T12:39:18+00:00

commit ed6473ddc704a2005b9900ca08e236ebb2d8540a upstream. We want to use kthread_stop() in order to ensure the threads are shut down before we tear down the nfs_callback_info in nfs_callback_down.

SUNRPC: Add a server side per-connection limit

2016-07-13T19:53:48+00:00

Allow the user to limit the number of requests serviced through a single connection, to help prevent faster clients from starving slower clients. Signed-off-by: Trond Myklebust Signed-off-by: J. Bruce Fields

mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage

2016-04-04T17:41:08+00:00

Mostly direct substitution with occasional adjustment or removing outdated comments. Signed-off-by: Kirill A. Shutemov Acked-by: Michal Hocko Signed-off-by: Linus Torvalds

nfsd/sunrpc: factor svc_rqst allocation and freeing from sv_nrthreads refcounting

2015-08-10T20:05:44+00:00

In later patches, we'll want to be able to allocate and free svc_rqst structures without monkeying with the serv->sv_nrthreads refcount. Factor those pieces out of their respective functions. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: move pool_mode definitions into svc.h

2015-08-10T20:05:43+00:00

In later patches, we're going to need to allow code external to svc.c to figure out what pool_mode is in use. Move these definitions into svc.h to prepare for that. Also, make the svc_pool_map object available and exported so that other modules can peek in there to get insight into what pool mode is in use. Likewise, export svc_pool_map_get/put function to make it safe to do so. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: abstract out svc_set_num_threads to sv_ops

2015-08-10T20:05:43+00:00

Add an operation that will do setup of the service. In the case of a classic thread-based service that means starting up threads. In the case of a workqueue-based service, the setup will do something different. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: turn enqueueing a svc_xprt into a svc_serv operation

2015-08-10T20:05:42+00:00

For now, all services use svc_xprt_do_enqueue, but once we add workqueue-based service support, we'll need to do something different. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: move sv_module parm into sv_ops

2015-08-10T20:05:41+00:00

...not technically an operation, but it's more convenient and cleaner to pass the module pointer in this struct. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: move sv_function into sv_ops

2015-08-10T20:05:41+00:00

Since we now have a container for holding svc_serv operations, move the sv_function into it as well. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: add a new svc_serv_ops struct and move sv_shutdown into it

2015-08-10T20:05:40+00:00

In later patches we'll need to abstract out more operations on a per-service level, besides sv_shutdown and sv_function. Declare a new svc_serv_ops struct to hold these operations, and move sv_shutdown into this struct. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields
