[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 03/13] python: remove flask related libxc python bindings
Mostly for historical reasons Xen includes Python bindings for libxc.
They have been used by xm/xend in the past but nowadays there is no
user of any flask related python binding left. Remove them.
