[Bug 1619918] Re: lsattr 32bit does not work on 64bit kernel (Inappropriate ioctl error)

[Theodore Ts'o]

This is not an e2fsprogs bug, but a bug in the kernel.   The fix is in
mainline as of v4.7, commit id: 4c63c2454eff996.  It needs to be ported
to the Ubuntu Trusted (and other Ubuntu LTS) kernels.

Title:
  lsattr 32bit does not work on 64bit kernel (Inappropriate ioctl error)

Status in e2fsprogs package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  New

Bug description:
  I run an amd64 kernel on trusty.  The e2fsprogs package was still the
  32 bit i386 variety.  This lead to the following situation (for
  essentially all files on a btrfs partition).

  $ lsattr /lib/modules/3.13.0-95-generic/kernel/drivers/staging/lustre/lustre/ptlrpc/ptlrpc.ko
  lsattr: Inappropriate ioctl for device While reading flags on /lib/modules/3.13.0-95-generic/kernel/drivers/staging/lustre/lustre/ptlrpc/ptlrpc.ko

  The problem was resolved by installing e2fsprogs:amd64.
