When mballoc is enabled, block allocation for old block-based files are allocated using mballoc allocator instead of old block-based allocator. The old ext3 block reservation is turned off when mballoc is turned on. However, the in-core preallocation is not enabled for block-based/ non-extent based file block allocation. This result in performance regression, as now we don't have "reservation" ore in-core preallocation to prevent interleaved fragmentation in multiple writes workload. This patch fix this by enable per inode in-core preallocation for non extent files when mballoc is used.
