From 015c6033068208d6227612c878877919f3fcf6b6 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 5 Nov 2019 17:44:19 +0100 Subject: jbd2: Fix statistics for the number of logged blocks jbd2 statistics counting number of blocks logged in a transaction was wrong. It didn't count the commit block and more importantly it didn't count revoke descriptor blocks. Make sure these get properly counted.
