Title:
  hyper-v: Enabling dynamic memory on Hyper-V may lead to persistent
  load value of 1

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  It appears that if you enable dynamic memory on Hyper-V, and then run
  the top command then load metrics may always show 1 for the 1 minute
  average (See attached image). This is because the ballooning mechanism
  sleeps in uninterruptible mode which adds to the system load metric.
  Please use the following upstream patch to eliminate this problem:

  Drivers: hv: Ballon: Make pressure posting thread sleep interruptibly

  http://git.kernel.org/cgit/linux/kernel/git/next/linux-
  next.git/commit/drivers/hv/hv_balloon.c?id=5dba4c56dfa660a85dc8e897990948cdec3734bf
