| |
Description: Adds ssleep_interruptible() to allow longer delays to occur in TASK_INTERRUPTIBLE, similarly to ssleep(). To be consistent with msleep_interruptible(), ssleep_interruptible() returns the remaining time left in the delay in terms of seconds. This required dividing the return value of msleep_interruptible() by 1000, thus a cast to (unsigned long) to prevent any floating point issues.
