Kernel: arch/x86/boot/bzImage is ready (#87) Building modules, stage 2. MODPOST 5340 modules free(): invalid pointer Aborted (core dumped) make[1]: *** [scripts/Makefile.modpost:94: __modpost] Error 134 make: *** [Makefile:1303: modules] Error 2 With patch 2 and doing make M=fs/cifs nsdeps from the root of the git tree I get $ make M=fs/cifs nsdeps Building modules, stage 2. MODPOST 1 modules Building modules, stage 2. MODPOST 1 modules ./scripts/nsdeps: 34: local: ./fs/cifs/cifsfs.c: bad variable name make: *** [Makefile:1710: nsdeps] Error 2 -- Thanks, Steve
