sched/swait: Rename to exclusive
Since swait basically implemented exclusive waits only, make sure
the API reflects that.
$ git grep -l -e "\<swake_up\>"
-e "\<swait_event[^ (]*"
-e "\<prepare_to_swait\>" | while read file;
do
sed -i -e 's/\<swake_up\>/&_one/g'
-e 's/\<swait_event[^ (]*/&_exclusive/g'
-e 's/\<prepare_to_swait\>/&_exclusive/g' $file;
done
With a few manual touch-ups.
