Hi, I've been working on adding support for 64 bit ino_t and 32 bit nlink_t. I have a patchset which is still work in progress, but I wasn't able to find time to continue the project for a month already. Notes: * Keep using 32 bit inodes in UFS and UFS boot code: UFS is a critical component and switching it to 64bit ino_t won't improve anything * Don't use nlink_t in UFS on-disk structs, introduce ufs_ino_t * Deprecate incomplete set of NetBSD emulation nstat* syscalls. Remove COMPAT_FREEBSD32 support which was never functional, mark as COMPAT8 * Implement both kernel level and libc compatibility shims, support COMPAT_FREEBSD32 * Add d_off (now unused) to struct dirent to facilitate removing cookies argument from VOP_READDIR. (both OpenSolaris and Linux do the same) * Libc compatibility shims for struct dirent users Tar archive of individual patches to make review easier. First several patches are bug fixes and can be commited as they are: https://github.com/downloads/glk/freebsd-ino64/freebsd-ino64-patch.tgz The same but as a single patch: https://github.com/downloads/glk/freebsd-ino64/freebsd-ino64.big.patch.gz Patches are against recent CURRENT: svn r215808. Code is also hosted on gitorious: http://gitorious.org/~glk/glk-freebsd-ino64 Thanks, Gleb.
