Subject: [PATCH for-next] io_uring: remove redundant NULL check before kfree
Date: Thu, 25 Jun 2026 20:07:33 +0530 [thread overview]
Message-ID: <20260625143733.975006-1-subasris1210@gmail.com> (raw)
Remove the unnecessary NULL pointer check before calling kfree()
in io_uring.c, as kfree() handles NULL arguments internally.
Reported by ifnullfree.cocci Coccinelle semantic
patch script.
