Subject: [PATCH v2 00/12] Interrupt fixes for leaks and warnings
Date: Sat, 24 Oct 2026 15:21:25 +0200 [thread overview]
Message-ID: <20261024132138.7239-1-david.marchand@redhat.com> (raw)
In-Reply-To: <20261021092318.1554295-1-david.marchand@redhat.com>
Following commit d770ee9caed0 ("interrupts: warn on leaked FDs"), a
number of leaks, but also false positive warnings have been identified.
The most notable change in this series is the removal of the interrupt
handle duplication. I concluded the principle is wrong (see patch 2
commitlog).
This will need some careful reviews.
