fscache_object_sleep_till_congested - Sleep until object wq is congested : Scheduler sleep timeout
Allow an object handler to sleep until the object workqueue is congested.
The caller must set up a wake up event before calling this and must have set the appropriate sleep mode (such as TASK_UNINTERRUPTIBLE) and tested its own condition before calling this function as no test is made here.
true is returned if the object wq is congested, false otherwise.

fscache_obtained_object - Note successful object lookup or creation : Object pointing to cookie to mark
Note successful lookup and/or creation, permitting those waiting to write data to a backing object to continue.
Note that after calling this, an object's cookie may be relinquished by the netfs, and so must be accessed with object lock held.
