# We have to override the new %%install behavior because, well... the kernel is special.
%global __spec_install_pre %{___build_pre}
# At the time of this writing (2019-03), RHEL8 packages use w2.xzdio
# compression for rpms (xz, level 2).
# Kernel has several large (hundreds of mbytes) rpms, they take ~5 mins
# to compress by single-threaded xz. Switch to threaded compression,
# and from level 2 to 3 to keep compressed sizes close to "w2" results.
#
# NB: if default compression in /usr/lib/rpm/redhat/macros ever changes,
# this one might need tweaking (e.g. if default changes to w3.xzdio,
# change below to w4T.xzdio):
#
# This is disabled on i686 as it triggers oom errors
%ifnarch i686
%define _binary_payload w3T.xzdio
%endif
Summary: The Linux kernel
# For a kernel released for public testing, released_kernel should be 1.
