Subject: [PATCH v2 22/24] file: Replace ksys_close with close_fd
Date: Fri, 20 Nov 2020 17:14:39 -0600	[thread overview]
Message-ID: <20201120231441.29911-22-ebiederm@xmission.com> (raw)
In-Reply-To: <87r1on1v62.fsf@x220.int.ebiederm.org>

Now that ksys_close is exactly identical to close_fd replace
the one caller of ksys_close with close_fd.
