Subject: sched: Use __always_inline on is_idle_task()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c94a88f341c9b8f05d8639f62bb5d95936f881cd;p=linux.git

sched: Use __always_inline on is_idle_task()

is_idle_task() may be used from noinstr functions such as
irqentry_enter(). Since the compiler is free to not inline regular
inline functions, switch to using __always_inline.
