This patch has been committed. Thanks --Rich commit 52f4953ac4a377f9f7fc870d2a81f30c3e5d3c7f Author: Eric Sandeen <sandeen@xxxxxxxxxxx> Date: Tue Mar 5 22:41:54 2013 +0000 xfstests: Fix hang when mkfs.btrfs isn't present My earlier patch (xfstests: handle new mkfs.btrfs -f option cleanly) had a flaw in that if set_prog_path mkfs.btrfs returns nothing, the grep will hang. Test for that case to avoid it, and just return the empty string in that case.
