Subject: [PATCH 1/4] kexec/kexec.c: Add the missing close() for fd used for kexec_file_load()
Date: Thu, 11 Jul 2019 01:24:26 +0530	[thread overview]
Message-ID: <1562788469-22935-2-git-send-email-bhsharma@redhat.com> (raw)
In-Reply-To: <1562788469-22935-1-git-send-email-bhsharma@redhat.com>

In kexec/kexec.c, we open() the kernel Image file and pass this file
descriptor to the kexec_file_load() system call, but never call a
corresponding close().

Fix the same via this patch.
