  "message": "ceph: file operations\n\nFile open and close operations, and read and write methods that ensure\nwe have obtained the proper capabilities from the MDS cluster before\nperforming IO on a file.  We take references on held capabilities for\nthe duration of the read/write to avoid prematurely releasing them\nback to the MDS.\n\nWe implement two main paths for read and write: one that is buffered\n(and uses generic_aio_{read,write}), and one that is fully synchronous\nand blocking (operating either on a __user pointer or, if O_DIRECT,\ndirectly on user pages).\n\nSigned-off-by: Sage Weil \u003csage@newdream.net\u003e\n",
