This is the stuff found in fs/fs-writeback.c. Currently I have tests to fsync millions of inodes concurrently, tests involving mounting and unmounting file systems, and other tests to tickle some starvation of big file situations. Has anyone else been bitten by writeback not performing correctly either in the past or now? If so please send me the situation so I can incorporate it into my tests and also make sure my new attempt at an implementation does not cause damage. These tests will end up in autotest on test.kernel.org so they will become something the whole community can use. mrubin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
