[libvirt] [PATCH 2/2] src: remove HAL node device driver

The HAL driver is not used by any supported Linux, the only possible user could be FreeBSD, but the official libvirt port disables HAL driver unconditionally which means probably nobody is using it there. Signed-off-by: Pavel Hrdina <phrdina(a)redhat.com&gt; --- HAL was deprecated on FreeBSD as well and the current supported device manager is *devd*. If there will be need to implement node device support on FreeBSD we can add a new DEVD driver or we can use libudev-devd project to support UDEV driver on FreeBSD. configure.ac | 3 +- docs/drvnodedev.html.in | 3 +- docs/hvsupport.pl | 2 +- libvirt.spec.in | 1 - m4/virt-hal.m4 | 10 +- po/POTFILES | 1 - src/node_device/Makefile.inc.am | 12 - src/node_device/node_device_driver.c | 10 +- src/node_device/node_device_driver.h | 5 - src/node_device/node_device_hal.c | 804 --------------------------- src/node_device/node_device_hal.h | 22 - 11 files changed, 9 insertions(+), 864 deletions(-) delete mode 100644 src/node_device/node_device_hal.c delete mode 100644 src/node_device/node_device_hal.h diff --git a/configure.ac b/configure.ac index fabec815db..cbec6b9e14 100644 --- a/configure.ac +++ b/configure.ac @@ -794,7 +794,7 @@ AC_SUBST([LV_LIBTOOL_OBJDIR]) with_nodedev=no; -if test "$with_hal" = "yes" || test "$with_udev" = "yes"; +if test "$with_udev" = "yes"; then with_nodedev=yes AC_DEFINE_UNQUOTED([WITH_NODE_DEVICES], 1, [with node device driver]) @@ -995,7 +995,6 @@ LIBVIRT_RESULT_FIREWALLD_ZONE LIBVIRT_RESULT_FUSE LIBVIRT_RESULT_GLUSTER LIBVIRT_RESULT_GNUTLS -LIBVIRT_RESULT_HAL LIBVIRT_RESULT_LIBISCSI LIBVIRT_RESULT_LIBNL LIBVIRT_RESULT_LIBPCAP diff --git a/docs/drvnodedev.html.in b/docs/drvnodedev.html.in index 71a8a57b0c..8582f18655 100644 --- a/docs/drvnodedev.html.in +++ b/docs/drvnodedev.html.in @@ -23,8 +23,7 @@ (<a href="http://wiki.libvirt.org/page/NPIV_in_libvirt">more info about NPIV)</a>).
