  "message": "[PATCH] direct-io: sync and invalidate file region when falling back to buffered write\n\nWhen direct-io falls back to buffered write, it will just leave the dirty data\nfloating about in pagecache, pending regular writeback.\n\nBut normal direct-io semantics are that IO is synchronous, and that it leaves\nno pagecache behind.\n\nSo change the fallback-to-buffered-write code to sync the file region and to\nthen strip away the pagecache, just as a regular direct-io write would do.\n\nAcked-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nCc: Zach Brown \u003czach.brown@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
