      "message": "FS-Cache: Implement the cookie management part of the netfs API\n\nImplement the cookie management part of the FS-Cache netfs client API.  The\ndocumentation and API header file were added in a previous patch.\n\nThis patch implements the following three functions:\n\n (1) fscache_acquire_cookie().\n\n     Acquire a cookie to represent an object to the netfs.  If the object in\n     question is a non-index object, then that object and its parent indices\n     will be created on disk at this point if they don\u0027t already exist.  Index\n     creation is deferred because an index may reside in multiple caches.\n\n (2) fscache_relinquish_cookie().\n\n     Retire or release a cookie previously acquired.  At this point, the\n     object on disk may be destroyed.\n\n (3) fscache_update_cookie().\n\n     Update the in-cache representation of a cookie.  This is used to update\n     the auxiliary data for coherency management purposes.\n\nWith this patch it is possible to have a netfs instruct a cache backend to\nlook up, validate and create metadata on disk and to destroy it again.\nThe ability to actually store and retrieve data in the objects so created is\nadded in later patches.\n\nNote that these functions will never return an error.  _All_ errors are\nhandled internally to FS-Cache.\n\nThe worst that can happen is that fscache_acquire_cookie() may return a NULL\npointer - which is considered a negative cookie pointer and can be passed back\nto any function that takes a cookie without harm.  A negative cookie pointer\nmerely suppresses caching at that level.\n\nThe stub in linux/fscache.h will detect inline the negative cookie pointer and\nabort the operation as fast as possible.  This means that the compiler doesn\u0027t\nhave to set up for a call in that case.\n\nSee the documentation in Documentation/filesystems/caching/netfs-api.txt for\nmore information.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Steve Dickson \u003csteved@redhat.com\u003e\nAcked-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nTested-by: Daire Byrne \u003cDaire.Byrne@framestore.com\u003e\n"
