From a627b0a7c15ee4d2c87a86d5be5c8167382e8d0d Mon Sep 17 00:00:00 2001 From: Eric Whitney Date: Sun, 30 Jul 2017 22:30:11 -0400 Subject: ext4: remove unused metadata accounting variables Two variables in ext4_inode_info, i_reserved_meta_blocks and i_allocated_meta_blocks, are unused. Removing them saves a little memory per in-memory inode and cleans up clutter in several tracepoints. Adjust tracepoint output from ext4_alloc_da_blocks() for consistency and fix a typo and whitespace near these changes.
