[ 018/147] tools/hv: Fix exit() error code

From: Ben Hutchings
Date: Sun Oct 14 2012 - 11:17:23 EST


3.2-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

commit 6bb22fea25624ab593eee376fa5fb82d1b13f45a upstream.

Linux native exit codes are 8-bit unsigned values. exit(-1) results
in an exit code of 255, which is usually reserved for shells reporting
'command not found'. Use the portable value EXIT_FAILURE. (Not that
this matters much for a daemon.)

[bwh: Backported to 3.2: drop changes to exit() calls not in this version]
