Its filename was lib-add-allocation-tagging-support-for-memory-allocation-profiling-fix-4.patch This patch was dropped because it was folded into lib-add-allocation-tagging-support-for-memory-allocation-profiling.patch ------------------------------------------------------ From: Suren Baghdasaryan Subject: lib: fix alloc_tag_init() to prevent passing NULL to PTR_ERR() Date: Tue, 16 Apr 2024 17:33:49 -0700 codetag_register_type() never returns NULL, yet IS_ERR_OR_NULL() is used to check its return value. This leads to a warning about possibility of passing NULL to PTR_ERR(). Fix that by using IS_ERR() to exclude NULL.
