Created attachment 12879 [details] debian-testing 5.8 kernel fix Hi, down_read (&mm->mmap_sem); has evolved to mmap_read_lock (mm); Same things for up_{read,write} and *_trylock() I fixed the source code and I am providing a patch. Thanks you :-)) P.S.: I also included generated/utsrelease.h instead of linux/vermagic.h to avoid an new pre-processor #error statement
git master stap works on this kernel due to patches a few months ago
