From fe7748f097b3b3ad99d600bf58ddf75cb423c35c Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 19 Jul 2017 13:35:51 -0700 Subject: [PATCH] generic/421: stop test from hanging on buggy kernels On some buggy kernels, the 'find' command in generic/421 encounters a "Permission denied" error when trying to search $dir, so it doesn't find the file it's supposed to. This causes 'cat' to read from stdin, hanging the test. Quote the argument to cat to make the test fail right away rather than hanging.
