- Add patch getty-generator-with-serial-3270-tty.patch to avoid harmless error messages on not existing getty@3270 files - Replace systemd-big-endian-reply-matching.patch with upstream 0001-sd-bus-don-t-look-for-a-64bit-value-when-we-only-hav.patch to solve broken systemd communication with and over dbus (bnc#866732) - Readd patch 1008-add-msft-compability-rules.patch for older code base as 13.1 - Modify pre_checkin.sh to throw an error if a patch will be applied which modifies one of Makefile.am, Makefile.in, or configiure.ac as this breaks bootstrapping - Add second version of make-209-working-on-older-dist.patch to be able to apply for bootstrapping version - Don't require non-existing binutils-gold - Avoid file conflict between udev and systemd (bnc#868230) - Modify patch module-load-handle-SUSE-etc-sysconfig-kernel-module-list.patch to ignore if /etc/sysconfig/kernel does not exist (bnc#865834) - Add patch systemd-big-endian-reply-matching.patch make sure that systemd can talk with dbus-daemon even on big endian systems (bnc#866732) ----------------------------------------------------------------- - Due to previous reason, resurrect systemd-dbus-system-bus-address.patch - Removed pkgconfig(dbus-1) BuildRequires - with 209 and newer, itis only needed for quering default DBus directories, which we nowpass to configure.

Subject: [PATCH] Persistent by_path links for ata devices
|
|
|
|
With newer kernel we have the 'port_no' attribute,
|
|
which allows us to construct a valid ata by-path link.
|
|
|
|
With this patch ATA links of the form
|
|
|
|
ata-<port>.[01]
|
|
|
|
(for master/slave devices) or
|
|
|
|
ata-<port>.<pmp>.0
|
|
|
|
(for devices behind port multipliers)
|
|
are generated.
|
