[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] [xen-unstable] Make domctl/sysctl interfaces 32-/64-bit invariant.
# HG changeset patch
# User kfraser@xxxxxxxxxxxxxxxxxxxxx
# Date 1169656399 0
# Node ID 30af6cfdb05c6e56b3024e8be4abb3a10fc41297
# Parent a94363b85e192540bf94c4da60adcf4176ecbdd0
Make domctl/sysctl interfaces 32-/64-bit invariant.
This kills off a fair amount of unpleasant CONFIG_COMPAT shimming and
avoids needing to keep the compat paths in sync as these interfaces
continue to develop.
