/* TODO: Fix: won't compile if it struct included in ifdef HAVE_LINUX_BTRFS_H */
it is better, sorry

I have some problem with compile, if i insert
btrfs_ioctl_defrag_range_args in  #ifndef HAVE_LINUX_BTRFS_H like
btrfs_ioctl_vol_args. I can't compile, because ifndef not insert this
code.
and i place btrfs_ioctl_defrag_range_args without ifndef, and only
after this, it compile.
I can't understand why i have this problem, and as a result, do not
know how to fix it.

it acceptable for fix 'TODO' spelling and resend? Or may be, some one
know how fix my problem above with more acceptable solution?
