Subject: [PATCHSET 0/2] Fix DEFER_TASKRUN ring resize flag manipulation
Date: Tue, 10 Mar 2026 08:45:47 -0600	[thread overview]
Message-ID: <20260310145521.68268-1-axboe@kernel.dk> (raw)

Hi,

Two patches here:

1) Fix adding local task_work during ring resize. There's a tiny gap
   where a NULL pointer would be used.

2) Same issue exists in the eventfd handling, so apply the same kind of
   fix there.

Thanks to Hao-Yu Yang for the report and initial fix attempt, and Pavel
for a good suggestion on how best to handle this.
