Subject: [PATCH v7 06/15] KVM: s390: remove kvm_s390_ from gisa static inline functions
Date: Thu, 31 Jan 2019 09:52:37 +0100 [thread overview]
Message-ID: <20190131085247.13826-7-mimu@linux.ibm.com> (raw)
In-Reply-To: <20190131085247.13826-1-mimu@linux.ibm.com>
This will shorten the length of code lines. All GISA related
static inline functions are local to interrupt.c.
