freezer: introduce freezer-friendly waiting macros
Introduce freezer-friendly wrappers around wait_event_interruptible() and wait_event_interruptible_timeout(), originally defined in <linux/wait.h>, to be used in freezable kernel threads. Make some of the freezable kernel threads use them. This is necessary for the freezer to stop sending signals to kernel threads, which is implemented in the next patch. Signed-off-by: Rafael J.
