Andrew Kryczka 2c9df9f9e5 Dynamic test whether sync_file_range returns ENOSYS (#5416) ... Summary: `sync_file_range` returns `ENOSYS` on Windows Subsystem for Linux even when using a supposedly supported filesystem like ext4. To handle this case we can do a dynamic check that a no-op `sync_file_range` invocation, which is accomplished by passing zero for the `flags` argument, succeeds. Also I rearranged the function and comments to hopefully make it more easily understandable.
