+X-Dgit-Generated: 1.44.5-1 622e62942104d357912480e49c5b5524588cf45f
+Subject: Revert "e4defrag: use 64-bit counters to track # files defragged"
+
+This reverts commit 3293ea9ecbe1d622f9cf6c41d705d82fbae6a3e3.
+
+This wasn't really the right fix, since there can't be more than 2**32
+files in a file system. The real issue is when the number of files in
+a directory change during the e4defrag run.
