Subject: [PATCH v3 04/10] vfio_pci: make common functions be extern
Date: Thu, 21 Nov 2019 19:23:41 +0800 [thread overview]
Message-ID: <1574335427-3763-5-git-send-email-yi.l.liu@intel.com> (raw)
In-Reply-To: <1574335427-3763-1-git-send-email-yi.l.liu@intel.com>
This patch makes the common functions (module agnostic functions) in
vfio_pci.c to extern. So that such functions could be moved to a common
source file.
*) vfio_pci_set_vga_decode
*) vfio_pci_enable
*) vfio_pci_disable
*) vfio_pci_ioctl
*) vfio_pci_read
*) vfio_pci_write
*) vfio_pci_mmap
*) vfio_pci_request
*) vfio_pci_fill_ids
*) vfio_pci_reflck_attach
*) vfio_pci_reflck_put
*) vfio_pci_probe_power_state
