The kernel doesn't build when enabling XEN_BLKDEV_TAP and CONFIG_XEN_BLKDEV_TAP2. The config selection should be made mutually exclusive.

Update: XEN_BLKDEV_TAP2 doesn't build because of the previously posted "multiple definitions" only with XEN_BLKDEV_TAP it builds nice :-)

+ 28 Jul 2011; Patrick Lauer <patrick@gentoo.org> +xen-sources-2.6.38.ebuild: + Bump for #366323, last standalone xen-sources before kernel 3.0 (or so we + hope)
Download of genpatches-2.6.38-4.base.tar.bz2 fails.
Just change K_GENPATCHES_VER to "8". I guessed this number but there are plenty of other versions.. I don't know which one is most suitable.
Compiling the kernel (sys-kernel/xen-sources-2.6.38) with CONFIG_XEN_BLKDEV_TAP and CONFIG_XEN_BLKDEV_TAP2 enabled has failed (https://bugs.gentoo.org/show_bug.cgi?id=366323#c3). With CONFIG_XEN_BLKDEV_TAP2 as a module it worked. I don't understand, if this bug was corrected ?
