    dm suspend: return -ERESTARTSYS instead of -EINTR
    
    [ Upstream commit 1e1fd567d32fcf7544c6e09e0e5bc6c650da6e23 ]
    
    This commit changes device mapper, so that it returns -ERESTARTSYS
    instead of -EINTR when it is interrupted by a signal (so that the ioctl
    can be restarted).
    
    The manpage signal(7) says that the ioctl function should be restarted if
    the signal was handled with SA_RESTART.
