[PATCH 03/10] fs: cifs: Replace CURRENT_TIME with current_fs_time()

[Deepa Dinamani <deepa.kernel@gmail.com>]

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.
