From 35973232b5cddd8b03dac2730cd1ca53137d1cd4 Mon Sep 17 00:00:00 2001 From: Xiongwei Song Date: Thu, 13 Apr 2023 22:34:48 +0800 Subject: slub: Correct the error code when slab_kset is NULL The -ENOSYS is inproper when kset_create_and_add call returns a NULL pointer, the failure more likely is because lacking memory, hence returning -ENOMEM is better.
