[libvirt] [PATCH] Add a define for NFS_SUPER_MAGIC

[Eric Blake]

According to Chris Lalancette on 3/3/2010 9:44 AM:
> Commit 3c12a67b766cce51b47861ccde2be41de369f832 added
> a dependency on the NFS_SUPER_MAGIC macro, which is

ACK.

>  #ifdef __linux__
>  #include <sys/vfs.h>
> -#include <linux/magic.h>
> -#endif
> +#ifndef NFS_SUPER_MAGIC
> +#define NFS_SUPER_MAGIC 0x6969
> +#endif /* NFS_SUPER_MAGIC */
> +#endif /* __linux__ */

Style question (and yet another thing for me to add to my pending HACKING
patch): any objections to indenting preprocessor directives to make it
easier to track nesting?  As in:

#ifdef __linux__
# include <sys/vfs.h>
# ifndef NFS_SUPER_MAGIC
#  define NFS_SUPER_MAGIC 0x6969
# endif /* NFS_SUPER_MAGIC */
#endif /* __linux__ */
