filemap_xip.c:(.text+0x19bd4): undefined reference to `ub_unused_privvm_inc'

Elton, could you please provide the corresponding CONFIG options (the ones
openvz sets/uses) ?

Sure, I think this is all:

CONFIG_VZ_QUOTA=m
# CONFIG_VZ_QUOTA_UNLOAD is not set
CONFIG_VZ_QUOTA_UGID=y


CONFIG_VE=y
CONFIG_VE_CALLS=m
CONFIG_VE_NETDEV=m
CONFIG_VE_IPTABLES=y
CONFIG_VZ_WDOG=m
CONFIG_VZ_CHECKPOINT=m

026.009-r1 in cvs, thanks.

Filed as OpenVZ bug #149 (http://bugzilla.openvz.org/149). Apparently this is
due to CONFIG_FS_XIP which is not used in "standard" configs.
