Comment 3 for bug 1416794

blkid doesn't recognize exfat.

The error seems to be in the file "libblkid/src/superblocks/exfat.c" in function "probe_exfat":
In line 124 "if (errno)" is always true because "errno" is already !=0 before "probe_exfat" is called.
The problem can be fixed by either adding "errno = 0;" to the beginning of the "probe_exfat" function or by removing the seemingly useless check altogether.
