Hi i cloned the centos6 repo and confirmed nilfs2 works fine! there's no kernel panics happend on my environment, lscp and unmount works well. thank you very much. then, i'm trying to build rpm package of the centos6 kmod. but i'm not familiar with rpm and kernel modules. i'm reusing SPEC file from centos5's nilfs srpm. kmodtool is renewed in RHEL6, replace with it. in SPEC file, build and install section, SPEC file calls make with "modules" and "modules_install" argument. Makefile in the centos6-kmod repo has no such rules. how should i fix Makefile or SPEC file? thanks.
