There are a number of bits of code sprinkled around the kernel to
set a thread flag if a certain condition is true, and clear it
otherwise.
To help make those call sites terser and less cumbersome, this
patch adds a new family of thread flag manipulators
update*_thread_flag([...,] flag, cond)
which do the equivalent of:
if (cond)
set*_thread_flag([...,] flag);
else
clear*_thread_flag([...,] flag);
