Subject: [PATCH] io_uring/fdinfo: show SQEs for no array setup
Date: Wed, 22 Oct 2025 13:56:07 -0700 [thread overview]
Message-ID: <20251022205607.4035359-1-kbusch@meta.com> (raw)
From: Keith Busch <kbusch@kernel.org>
The sq_head indicates the index directly in the submission queue when
the IORING_SETUP_NO_SQARRAY option is used, so use that instead of
skipping showing the entries.
