From 6d5c3aa84b3e431f2d0fc39c73c867d1a4dd8cff Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Tue, 14 Dec 2010 21:45:31 -0500 Subject: [PATCH] ext4: fix typo which broke '..' detection in ext4_find_entry() There should be a check for the NUL character instead of '0'. Fortunately the only thing that cares about this is NFS serving, which is why we didn't notice this in the merge window testing.
