Subject: [PATCH 1/5] efi: Fix debugobjects warning on efi_rts_work
Date: Wed, 14 Nov 2018 09:55:40 -0800
Message-ID: <20181114175544.12860-2-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20181114175544.12860-1-ard.biesheuvel@linaro.org>

From: Waiman Long <longman@redhat.com>

The commit 9dbbedaa6171 ("efi: Make efi_rts_work accessible to efi
page fault handler") converted efi_rts_work from an auto variable to a
global variable. However, when submitting the work, INIT_WORK_ONSTACK()
was still used causing the following complaint from debugobjects:

ODEBUG: object 00000000ed27b500 is NOT on stack 00000000c7d38760,
but annotated.

Change the macro to just INIT_WORK() to eliminate the warning.

Fixes: 9dbbedaa6171 ("efi: Make efi_rts_work accessible to efi page fault handler")
