sched/wait: Include <linux/wait.h> in <linux/swait.h>
kbuild bot reported against an intermediate RT patch that the build fails with: > In file included from include/linux/completion.h:12:0, > from include/linux/rcupdate_wait.h:10, > from kernel/rcu/srcutiny.c:27: > kernel/rcu/srcutiny.c: In function 'srcu_drive_gp': > >> include/linux/swait.h:172:7: error: implicit declaration of function '___wait_is_interruptible'; did you mean '__swait_event_interruptible'? > if (___wait_is_interruptible(state) && __int) { \ That error vanishes a few patches later (in the RT queue) because wait.h is then pulled in by other means. It does not seem to surface on !RT. I think that swait should include a header file for a function/macro (___wait_is_interruptible()) it is using.
