Subject: Please apply e74798f2f8e1 ("genirq/proc: Fix missing CPU header in /proc/interrupts") to 7.3.y and 7.2.y
Date: Thu, 22 Oct 2026 16:56:09 -0500 [thread overview]
Message-ID: <20261022215609.2203554-1-harisokn@amazon.com> (raw)
Please pick up upstream commit e74798f2f8e1 ("genirq/proc: Fix missing
CPU header in /proc/interrupts") for 7.3.y and 7.2.y. It applies
cleanly to both branches.
It fixes 171cc0d9eed1 ("genirq/proc: Speed up /proc/interrupts
iteration"), which landed in v7.2-rc1, so both series are affected. The
fix was merged into mainline after v7.3, so it is not in a release yet.
The bug causes the CPU header to be missing from /proc/interrupts on
large systems, such as the 192-CPU 8g.48xl and 384-CPU 8i.96xl AWS
instance types, which breaks userspace tools that expect the header.
Thanks,
