https://svnweb.freebsd.org/base/stable/11/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_ioctl.c?revision=339111&view=markup#l7146 This code uses some xdr(3) functions to parse zpool.cache and kernel-side implementation of xdr(3) is contained in krpc.ko Out of curiosity, I've commented out mentioned MODULE_DEPEND(zfsctrl, krpc, 1, 1, 1), rebuilt zfs.ko and tried to kldload it using UFS-only system having no NFS code in the kernel and it failed with a note in dmesg: link_elf: symbol xdrmem_create undefined _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
