5*4882a593SmuzhiyunDescription:
6*4882a593Smuzhiyun		The maximum number of times the balloon driver will
7*4882a593Smuzhiyun		attempt to increase the balloon before giving up.  See
8*4882a593Smuzhiyun		also 'retry_count' below.
9*4882a593Smuzhiyun		A value of zero means retry forever and is the default one.

15*4882a593SmuzhiyunDescription:
16*4882a593Smuzhiyun		The limit that 'schedule_delay' (see below) will be
17*4882a593Smuzhiyun		increased to. The default value is 32 seconds.

23*4882a593SmuzhiyunDescription:
24*4882a593Smuzhiyun		The current number of times that the balloon driver
25*4882a593Smuzhiyun		has attempted to increase the size of the balloon.
26*4882a593Smuzhiyun		The default value is one. With max_retry_count being
27*4882a593Smuzhiyun		zero (unlimited), this means that the driver will attempt
28*4882a593Smuzhiyun		to retry with a 'schedule_delay' delay.

34*4882a593SmuzhiyunDescription:
35*4882a593Smuzhiyun		The time (in seconds) to wait between attempts to
36*4882a593Smuzhiyun		increase the balloon.  Each time the balloon cannot be
37*4882a593Smuzhiyun		increased, 'schedule_delay' is increased (until
38*4882a593Smuzhiyun		'max_schedule_delay' is reached at which point it
39*4882a593Smuzhiyun		will use the max value).
