[ros-diffs] [fireball] 36830: - VFAT fixes: Actually perform a mandatory call to CcPurgeCacheSection during file deletion (fixes real NT5 cache manager attempts to write section of a deleted file). - VFAT fixes: When querying FileStandardInformation, NT's fastfat driver sets NumberOfLinks to 1, ours sets it to 0 somewhy. Change to 1 for compatibility. - A couple of debug prints improvements in VFAT. - Comment out UNIMPLEMENTED in CcPurgeCacheSection to prevent debug messages flood.
