Subject: [PATCH] mm/slab: call __kmalloc_noprof() when size isn't builtin constant in kmalloc_array_noprof()
Date: Sat, 1 Mar 2025 16:37:20 +0800 [thread overview]
Message-ID: <20250301083720.380063-1-yebin@huaweicloud.com> (raw)
From: Ye Bin <yebin10@huawei.com>
If 'n' or 'size' isn't builtin constant just call __kmalloc_noprof()
in kmalloc_array_noprof().
Fixes: 7bd230a26648 ("mm/slab: enable slab allocation tagging for kmalloc and friends")
