+Subject: [PATCH] journald,ratelimit: fix wrong calculation of burst_modulate()
+ (#4218)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch fixes wrong calculation of burst_modulate(), which now calculates
+the values smaller than really expected ones if available disk space is
+strictly more than 1MB.
+
+In particular, if available disk space is strictly more than 1MB and strictly
+less than 16MB, the resulted value becomes smaller than its original one.
+
+>>> (math.log2(1*1024**2)-16) / 4
+1.0
+>>> (math.log2(16*1024**2)-16) / 4
+2.0
+>>> (math.log2(256*1024**2)-16) / 4
+3.0
+-> This matches the comment in the function.
