    SubjectRe: xfs compat_ioctl?
    I still get these on 2.6.30.4 on sparc64 (32-bit userspace a la Debian etch):

    sparcy:~# uname -a
    Linux sparcy 2.6.30.4-sparcy #2 Sat Aug 1 21:14:46 CDT 2009 sparc64 GNU/Linux
    sparcy:~# file $(which xfs_fsr)
    /usr/sbin/xfs_fsr: ELF 32-bit MSB executable, SPARC32PLUS, V8+ Required, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
    sparcy:~# dmesg | grep xfs | tail -5
    [62457.467755] ioctl32(xfs_fsr:18816): Unknown cmd fd(7) cmd(c0a8586d){t:'X';sz:168} arg(00028e30) on /export

    Haven't tried rolling my own xfs_progs binaries yet. xfs_db also fails with
    a "Bus error" immediately on startup, but that may be a completely different
    issue...
