+Subject: [PATCH] tuna: Add distinction between --spread and --move to error
+ message
+
+Currently, the command `tuna --cpus=CPU-LIST --spread` generates an
+error with the warning "tuna: --move requires a list of threads/irqs!".
+Similarly, when the command `tuna --threads=THREAD-LIST --spread` is
+run, it generates the warning "tuna: --move requires a cpu list!".
+
+This can be confusing to the user, especially with commands that use both
+the "--spread" and "--move" flags. The warning should specify "--spread"
+when that is the source of the error.
+
+Check whether the argument is a move or spread and update the warning
+string accordingly.
