Subject: [PATCH v2 04/13] vfio_pci: make common functions be extern
Date: Thu,  5 Sep 2019 15:59:21 +0800	[thread overview]
Message-ID: <1567670370-4484-5-git-send-email-yi.l.liu@intel.com> (raw)
In-Reply-To: <1567670370-4484-1-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
