With Linux 3.18-rc1 having came one week early, the EXT4 file-system pull request didn't end up landing until today. However, the EXT4 changes aren't overly exciting for the 3.18 merge window.

The EXT4 changes for the Linux 3.18 kernel merge window come down to mostly just code clean-ups and bug fixes along with some minor journal optimizations.

Those interested in more details on the EXT4 Linux 3.18 changes can see the Git merge. Once Linux 3.18 settles down more I'll be around with my usual benchmarks of the EXT4, F2FS, XFS, and Btrfs file-system benchmarks for SSDs and HDDs.
