Subject: Re: [PATCH v2 2/7] s390/pci: Fix resource leak in zpci MSI setup
Date: Mon, 05 Oct 2026 12:17:54 +0000 [thread overview]
Message-ID: <20261005121755.361BC1F000FF@smtp.kernel.org> (raw)

> If airq_iv_create() fails in __alloc_airq(), the zpci_sbv bit allocated
> by airq_iv_alloc_bit() is never freed. This permanently leaks one of the
> ZPCI_NR_DEVICES summary bits, reducing system capacity with each failed
> device hotplug. In systems with repeated device insertion failures or
> under memory pressure, all summary bits can be exhausted, preventing new
> PCI devices from being added until reboot.

> Add proper error handling to free the zpci_sbv bit and reset zdev->aisb
