  "message": "coda: remove CODA_STORE/CODA_RELEASE upcalls\n\nThis is an variation on the patch sent by Christoph Hellwig which kills\nfile_count abuse by the Coda kernel module by moving the coda_flush\nfunctionality into coda_release.  However part of reason we were using the\ncoda_flush callback was to allow Coda to pass errors that occur during\nwriteback from the userspace cache manager back to close().\n\nAs Al Viro explained on linux-fsdevel, it is impossible to guarantee that\nsuch errors can in fact be returned back to the caller.  There are many\ncases where the last reference to a file is not released by the close\nsystem call and it is also impossible to pick some close as a \u0027last-close\u0027\nand delay it until all other references have been destroyed.\n\nThe CODA_STORE/CODA_RELEASE upcall combination is clearly a broken design,\nand it is better to remove it completely.\n\nSigned-off-by: Jan Harkes \u003cjaharkes@cs.cmu.edu\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@ftp.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
