  "message": "fscache: Implement cache registration\n\nImplement a register of caches and provide functions to manage it.\n\nTwo functions are provided for the cache backend to use:\n\n (1) Acquire a cache cookie:\n\n\tstruct fscache_cache *fscache_acquire_cache(const char *name)\n\n     This gets the cache cookie for a cache of the specified name and moves\n     it to the preparation state.  If a nameless cache cookie exists, that\n     will be given this name and used.\n\n (2) Relinquish a cache cookie:\n\n\tvoid fscache_relinquish_cache(struct fscache_cache *cache);\n\n     This relinquishes a cache cookie, cleans it and makes it available if\n     it\u0027s still referenced by a network filesystem.\n\nNote that network filesystems don\u0027t deal with cache cookies directly, but\nrather go straight to the volume registration.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nReviewed-by: Jeff Layton \u003cjlayton@kernel.org\u003e\ncc: linux-cachefs@redhat.com\nLink: https://lore.kernel.org/r/163819587157.215744.13523139317322503286.stgit@warthog.procyon.org.uk/ # v1\nLink: https://lore.kernel.org/r/163906889665.143852.10378009165231294456.stgit@warthog.procyon.org.uk/ # v2\nLink: https://lore.kernel.org/r/163967085081.1823006.2218944206363626210.stgit@warthog.procyon.org.uk/ # v3\nLink: https://lore.kernel.org/r/164021494847.640689.10109692261640524343.stgit@warthog.procyon.org.uk/ # v4\n",
