  "message": "[PATCH] drop-pagecache\n\nAdd /proc/sys/vm/drop_caches.  When written to, this will cause the kernel to\ndiscard as much pagecache and/or reclaimable slab objects as it can.  THis\noperation requires root permissions.\n\nIt won\u0027t drop dirty data, so the user should run `sync\u0027 first.\n\nCaveats:\n\na) Holds inode_lock for exorbitant amounts of time.\n\nb) Needs to be taught about NUMA nodes: propagate these all the way through\n   so the discarding can be controlled on a per-node basis.\n\nThis is a debugging feature: useful for getting consistent results between\nfilesystem benchmarks.  We could possibly put it under a config option, but\nit\u0027s less than 300 bytes.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
