This one doesn't apply on -next. Is there a missing commit? Applying: mm: slub: add kernel address sanitizer support for slub allocator fatal: sha1 information is lacking or useless (mm/slub.c). Repository lacks necessary blobs to fall back on 3-way merge. Cannot fall back to three-way merge. Patch failed at 0007 mm: slub: add kernel address sanitizer support for slub allocator When you have resolved this problem run "git am --resolved". If you would prefer to skip this patch, instead run "git am --skip". To restore the original branch and stop patching run "git am --abort".
