Ah..I just noticed the changes in the nfsd code.
But in 2.6.27.10, can it be fixed by removing the lock_super in the vfat_lookup.? Because I saw some discussions long back of regressions due to replacing lock_kernel by lock_super in FAT code. Or should the sb mutex be unlocked before calling the callback filldir in the __fat_readdir?
Thanks, Fredrick
