Merging r4077, r4101, r4102: open_file_cache related fixes: *) Bugfix: open_file_cache lost is_directio flag. On file retest open_file_cache lost is_directio if file wasn't changed. This caused unaligned operations under Linux to fail with EINVAL. It wasn't noticeable with AIO though, as errors wasn't properly logged. *) Bugfix: open_file_cache did not update file info on retest. If file inode was not changed, cached file information was not updated on retest. As a result stale information might be cached forever if file attributes was changed and/or file was extended.
