Subject: [PATCH v3 1/7] efi: expose non-blocking set_variable() wrapper to efivars
Date: Mon, 14 Dec 2015 11:40:25 +0100	[thread overview]
Message-ID: <1450089631-26791-2-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1450089631-26791-1-git-send-email-ard.biesheuvel-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

From: Ard Biesheuvel <ard.biesheuvel-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

Commit 6d80dba1c9fe ("efi: Provide a non-blocking SetVariable()
operation") implemented a non-blocking alternative for the UEFI
SetVariable() invocation performed by efivars, since it may occur
in atomic context. However, this version of the function was never
exposed via the efivars struct, so the non-blocking versions was
not actually callable. Fix that.

Fixes: 6d80dba1c9fe ("efi: Provide a non-blocking SetVariable() operation")
