  Log Message:
  -----------
  With some popular multiplayer games (such as Counter-Strike: Global
Offensive) the Linux Steam client likes to occasionally scan the game
process memory, presumably as part anti-cheat measures. Turns out
the client also expects each inode entry to be followed by a space
character, otherwise the parsing code crashes.

  Hyper-V: hn: Relinquish cpu in HN_LOCK to avoid deadlock

The try lock loop in HN_LOCK put the thread spinning on cpu if the lock
is not available. It is possible to cause deadlock if the thread holding
the lock is sleeping. Relinquish the cpu to work around this problem even
it doesn't completely solve the issue. The priority inversion could cause
the livelock no matter how less likely it could happen. A more complete
solution may be needed in the future.
