  "message": "9p: implement optional loose read cache\n\nWhile cacheing is generally frowned upon in the 9p world, it has its\nplace -- particularly in situations where the remote file system is\nexclusive and/or read-only.  The vacfs views of venti content addressable\nstore are a real-world instance of such a situation.  To facilitate higher\nperformance for these workloads (and eventually use the fscache patches),\nwe have enabled a \"loose\" cache mode which does not attempt to maintain\nany form of consistency on the page-cache or dcache.  This results in over\ntwo orders of magnitude performance improvement for cacheable block reads\nin the Bonnie benchmark.  The more aggressive use of the dcache also seems\nto improve metadata operational performance.\n\nSigned-off-by: Eric Van Hensbergen \u003cericvh@gmail.com\u003e\n",
