Subject: [PATCH] [FEAT VS1822] util_lockfile: fix includes
From: Matthew Rosato <mjrosato@linux.ibm.com>

Summary:     ap_tools: add ap-check and the ap device type to zdev   
Description: This feature adds multiple components in support of persistent
             configuration of vfio-ap mediated devices.

             The ap-check utility is added as a callout function for the
             mdevctl utility.  This allows for meaningful error messages to be
             presented to end-users when vfio-ap configuration errors are
             detected while using mdevctl to create/modify vfio-ap mediated
             devices.

             Additionally, the 'ap' device type is added to zdev, providing a
             command-line interface for managing the apmask and aqmask, which
             determine what AP resources are available for vfio-ap usage.
             'chzdev' is updated to allow for modifying the active masks as
             well as to specify persistent mask values via a udev rule.
             'lszdev' is updated to allow for querying of the active and
             persistent mask values.

Upstream-Description:

             util_lockfile: fix includes

             The 'unistd.h' header was missing. Under some circumstances the
             -D_GNU_SOURCE gcc flag does not trigger including that file.
             Therefore, explicitly include this file here.
