2016-03-30staging/lustre/clio: cl_lock simplificationJinshan Xiong33-5525/+1168
In this patch, the cl_lock cache is eliminated. cl_lock is turned into a cacheless data container for the requirements of locks to complete the IO. cl_lock is created before I/O starts and destroyed when the I/O is complete. cl_lock depends on LDLM lock to fulfill lock semantics. LDLM lock is attached to cl_lock at OSC layer. LDLM lock is still cacheable. Two major methods are supported for cl_lock: clo_enqueue and clo_cancel. A cl_lock is enqueued by cl_lock_request(), which will call clo_enqueue() methods for each layer to enqueue the lock. At the LOV layer, if a cl_lock consists of multiple sub cl_locks, each sub locks will be enqueued correspondingly. At OSC layer, the lock enqueue request will tend to reuse cached LDLM lock; otherwise a new LDLM lock will have to be requested from OST side. cl_lock_cancel() must be called to release a cl_lock after use. clo_cancel() method will be called for each layer to release the resource held by this lock. At OSC layer, the reference count of LDLM lock, which is held at clo_enqueue time, is released. LDLM lock can only be canceled if there is no cl_lock using it.

It used to check each page in the readahead window is covered by a lock underneath, now cpo_page_is_under_lock() provides @max_index to help decide the maximum ra window. @max_index can be modified by OSC to extend the maximum lock region, to align stripe boundary at LOV, and to make sure the readahead region at least covers read region at LLITE layer.
