fat: don't use free_clusters for fat32
It seems that the recent Windows changed specification, and it's undocumented. Windows doesn't update ->free_clusters correctly. This patch doesn't use ->free_clusters by default. (instead, add "usefree" for forcing to use it) Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Cc: Juergen Beisert <juergen127@kreuzholzen.de> Cc: Andreas Schwab <schwab@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
