13 ext4: remove unused metadata accounting variables
14
15 Two variables in ext4_inode_info, i_reserved_meta_blocks and
16 i_allocated_meta_blocks, are unused. Removing them saves a little
17 memory per in-memory inode and cleans up clutter in several tracepoints.
18 Adjust tracepoint output from ext4_alloc_da_blocks() for consistency
19 and fix a typo and whitespace near these changes.
