71 This causes fscache to send the cache backend off to look up/create resources
88 actually required and it can use the fscache I/O API directly.
112 fscache will look up or create a cache cookie of that name and will use a cache
123 also return a NULL volume cookie if fscache is not enabled. It is safe to

184 This will cause fscache to either commit the storage backing the cookie or
192 tell fscache when it intends to use the cookie (typically done on file open)
201 The *use* function tells fscache that it will use the cookie and, additionally,

122 to tell fscache that a volume has been withdrawn. This waits for all
