From: Cédric Le Goater Date: Thu, 1 Jul 2021 13:27:50 +0000 (+0200) Subject: genirq: Improve "hwirq" output in /proc and /sys/ X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d92df42d7685445a2b6c815d9230d9699d9d400b;p=linux.git genirq: Improve "hwirq" output in /proc and /sys/ The HW IRQ numbers generated by the PCI MSI layer can be quite large on a pSeries machine when running under the IBM Hypervisor and they appear as negative. Use '%lu' instead to show them correctly.
