qemu fails to build on 4.5-rc1

[Pranith Kumar]

Hi Dave,

Commit 334e580a6f97 ("fs: XFS_IOC_FS[SG]SETXATTR to
FS_IOC_FS[SG]ETXATTR promotion") breaks building latest qemu as
follows:

In file included from /usr/include/xfs/xfs.h:58:0,
                 from /home/pranith/qemu/block/raw-posix.c:96:
/usr/include/xfs/xfs_fs.h:42:8: error: redefinition of âstruct fsxattrâ
 struct fsxattr {
        ^
In file included from /home/pranith/qemu/block/raw-posix.c:59:0:
/usr/include/linux/fs.h:155:8: note: originally defined here
 struct fsxattr {
        ^
/home/pranith/qemu/rules.mak:57: recipe for target 'block/raw-posix.o' failed

I think this is caused by moving the fsxattr struct around. Any
suggestion on how to fix this?

Thanks,
