Subject: [cocci] [PATCH] coccinelle: kmalloc_obj: Remove default GFP_KERNEL arg
Date: Fri, 20 Mar 2026 10:51:18 -0700	[thread overview]
Message-ID: <20260320175113.work.016-kees@kernel.org> (raw)

Remove any GFP_KERNEL arguments found in the new kmalloc_obj-family
helpers. This captures the script used in commit 189f164e573e ("Convert
remaining multi-line kmalloc_obj/flex GFP_KERNEL uses").
