CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_fs_time() instead.
Change signature of helper cifs_all_info_to_fattr since it now needs both super_block and cifs_sb_info.
Note: The inode timestamps read from the server are assumed to have correct granularity and range.
