Dear Ryusuke Konishi-san, The script ./scripts/checkkconfigsymbols.py identifies references to non-existing configs in the NILFS2 FILESYSTEM: NILFS_POSIX_ACL Referencing files: fs/nilfs2/nilfs.h NILFS_XATTR Referencing files: fs/nilfs2/nilfs.h, fs/nilfs2/super.c I assume this filesystem support is simply not yet developed to support those two configs fully, and these code blocks are just some first steps in that direction, but are currently just intended to be dead code in the repository. If you do not see this support to be added in the future, you could also just delete these ifdef blocks and these references to non-existing configs. This is just to share this information with you; there is no need for further action. Best regards, Lukas
