Fixes build failure with --enable-xfsctl and new linux headers (>=4.5) and older xfsprogs(<4.5): In file included from /usr/include/xfs/xfs.h:38:0, from /var/tmp/portage/app-emulation/qemu-2.5.0-r1/work/qemu-2.5.0/block/raw-posix.c:97: /usr/include/xfs/xfs_fs.h:42:8: error: redefinition of ‘struct fsxattr’ struct fsxattr { ^ In file included from /var/tmp/portage/app-emulation/qemu-2.5.0-r1/work/qemu-2.5.0/block/raw-posix.c:60:0: /usr/include/linux/fs.h:155:8: note: originally defined here struct fsxattr {
This is really a bug in the system headers, but we can work around it by defining HAVE_FSXATTR in the QEMU headers if linux/fs.h provides the struct, so that xfs_fs.h doesn't try to define it as well.
