parent 49313cdac7b34c9f7ecbb1780cfc648b1c082cd7 (v2.6.32-1-g49313cd) commit ff48c08e1c05c67e8348ab6f8a24de8034e0e34d Author: Jan Engelhardt <jengelh@xxxxxxxxxx> Date: Wed Dec 9 22:57:36 2009 +0100 btrfs: fix missing last-entry in readdir(3) When one does a 32-bit readdir(3), the last entry of a directory is missing. This is however not due to passing a large value to filldir, but it seems to have to do with glibc doing telldir or something quirky. In any case, this patch fixes it in practice.
