In get_contents function (fs/fat/fat.c),

There is code that checks the return value of get_fatent() at 360th line.

 

355                 /* search for consecutive clusters */

356                 while(actsize < filesize) {

357                         newclust = get_fatent(mydata, endclust);

358                         if((newclust -1)!=endclust)

359                                 goto getit;

360                         if (newclust <= 0x0001 || newclust >= 0xfff0) {

 

I think this comparison ( >= 0xfff0 ) is only for FAT16.

FAT32 value can be much larger.

Is this a bug?
