[PATCH 20/39] net/ip_vs_sync: replace schedule_timeout() with ssleep()

[Nishanth Aravamudan <nacc@xxxxxxxxxx>]

Hi,

Please consider applying.

Description: Use ssleep() instead of schedule_timeout() to guarantee the task
delays as expected. The first two replacements use TASK_INTERRUPTIBLE but do not
check for signals, so ssleep() should be appropriate.
