Subject: [PATCH v1 3/4] s390x:irq: make IRQ handler weak
Date: Wed, 13 Nov 2019 13:23:18 +0100 [thread overview]
Message-ID: <1573647799-30584-4-git-send-email-pmorel@linux.ibm.com> (raw)
In-Reply-To: <1573647799-30584-1-git-send-email-pmorel@linux.ibm.com>
Having a weak function allows the tests programm to declare its own IRQ
handler.
This is helpfull when developping I/O tests.
