Subject: [PATCH] NETLINK: Put {IFA,IFLA}_{RTA,PAYLOAD} macros back for userspace.
X-Git-Tag: v2.6.19.1~1
X-Git-Url: https://git.fsl.cs.sunysb.edu/?a=commitdiff_plain;h=f558fdfaa8d62e33ef47a819d1ca659a8f9e1f1a;p=unionfs-2.6.39.y.git

[PATCH] NETLINK: Put {IFA,IFLA}_{RTA,PAYLOAD} macros back for userspace.

GLIBC uses them etc.

They are guarded by ifndef __KERNEL__ so nobody will start
accidently using them in the kernel again, it's just for
userspace.
