Hello > > +#include <linux/kallsysms.h> > > Typo? #include <linux/kallsysms.h> is needed to be able to read KSYM_NAME_LEN: https://elixir.bootlin.com/linux/v6.13/source/include/linux/kallsyms.h#L18 In the file insn_decoder_test.c, is added otherwise, when configuring that test with CONFIG_X86_DECODER_SELFTEST, you would get the error ``` arch/x86/tools/insn_decoder_test.c:110:24: error: ‘KSYM_NAME_LEN’ undeclared (first use in this function) 110 | #define BUFSIZE (256 + KSYM_NAME_LEN) ``` This was proposed here: https://lore.kernel.org/lkml/Y9ES4UKl%2F+DtvAVS@xxxxxxxxx/ Cheers, Sergio Sergio
