2 			  FS-CACHE CACHE BACKEND API
5 The FS-Cache system provides an API by which actual caches can be supplied to
6 FS-Cache for it to then serve out to network filesystems and other interested
38 The cache should then be registered with FS-Cache by passing a pointer to the
47  (*) "fsdef" which should point to the object representation for the FS-Cache
49      here.  FS-Cache keeps the caller's reference to the index object if
82  (2) that of one of the processes in the FS-Cache thread pool.
89 This is left to the cache to handle; FS-Cache makes no effort in this regard.
96 The cache may present data to the outside world through FS-Cache's interfaces
108  (*) Index/Data file FS-Cache representation cookie:
139      passed to FS-Cache when requested by the appropriate cache operation.  In
145      using "OBJ%x" to be consistent with FS-Cache.
153  (*) FS-Cache operation record:
165      FS-Cache has a pool of threads that it uses to give CPU time to the
176  (*) FS-Cache retrieval operation record:
185      A structure of this type is allocated by FS-Cache to record retrieval and
201  (*) FS-Cache storage operation record:
209      A structure of this type is allocated by FS-Cache to record outstanding
210      writes to be made.  FS-Cache itself enqueues this operation and invokes
219 The cache backend provides FS-Cache with a table of operations that can be
242      multiple lookup calls to turn it into a more convenient form.  FS-Cache
378      It should also call fscache_set_store_limit() to indicate to FS-Cache the

527 FS-CACHE UTILITIES
530 FS-Cache provides some utilities that a cache backend may make use of:
536      This tells FS-Cache that an I/O error occurred in the cache.  After this
579      This sets the limit FS-Cache imposes on the highest byte it's willing to
632      This must be called to inform FS-Cache that an object that belonged to a
642      This is called to indicate to FS-Cache that a lookup process for an object
657      This is called to indicate to FS-Cache that a lookup process for an object
715      This enqueues a retrieval record for processing by the FS-Cache thread
