Subject: [PATCH] rcu: change function declaration to bool
rcu_cpu_has_callbacks() is declared int but is actually returning bool and
all call-sites currently use it as bool so the declaration should be bool
as well.
Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>

./kernel/rcu/tree.c:3538 WARNING: return of wrong type
int != bool,
as the description of rcu_cpu_has_callbacks() states:
" * Return true if the specified CPU has any callback...."
this probably should be a bool
All (3) call sites are conditions and are treating it as boolean.
Patch was compile tested with x86_64_defconfig (implies CONFIG_TREE_RCU=y)
Patch is against 4.1-rc3 (localversion-next is -next-20150511)
