Subject: [PATCH] init: fix error check in clean_path()
Date: Fri,  4 Sep 2020 09:53:32 -0400	[thread overview]
Message-ID: <20200904135332.1130070-1-brho@google.com> (raw)
In-Reply-To: <20200728163416.556521-22-hch@lst.de>

init_stat() returns 0 on success, same as vfs_lstat().  When it replaced
vfs_lstat(), the '!' was dropped.

Fixes: 716308a5331b ("init: add an init_stat helper")
