Dbackend-api.txt2 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
