%description

The 'rt-setup' package configures details required by RHEL-RT environment.

  - creates realtime group

  - adds realtime limits configuration for PAM

  - adds /usr/bin/rt-setup-kdump to config kdump in RT

  - adds udev specific rules for threaded irqs and /dev/rtc access

  - adds /usr/bin/slub_cpu_partial_off to turn off cpu_partials in SLUB

  - adds net-socket timestamp static key daemon (rt-entsk)
