Do you have this patch applied to your working branch ? :

fs/fat: Initialize local variable finfo

fat_stat in fs/fat.c declares finfo but doesn't initialize it.
When get_fileinfo is called, fno->lfname and fno->lfsize are
tested but haven't been zeroed...This can lead to a wrong
behavior.

When I worked on MMC SPI, I had problems with long file names. This
uninitialized
varible was the root cause...
