The Linux 3.1 kernel updated the fops->fsync() callback yet again. They now pass the requested range and delegate the responsibility for calling filemap_write_and_wait_range() to the callback. In addition imutex is no longer held by the caller and the callback is responsible for taking the lock if required. This commit updates the code to provide a zpl_fsync() function for the updated API. Implementations for the previous two APIs are also maintained for compatibility. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #445
