Subject: Endless getdents() in vfat filesystem

Hi,

Using the attached disk image I observe that getdents() never returns
the end of the directory, i.e. mounting the disk image on a loopback
device and running 'ls' under strace shows an endless stream of:

getdents(3, /* 2 entries */, 32768)     = 48
getdents(3, /* 2 entries */, 32768)     = 48
getdents(3, /* 2 entries */, 32768)     = 48
...


Vegard
