Inline Data Support Comes To CephFS With Linux 3.19
Ceph, the distributed file-system that prides itself as having no single point of failure and being very scalable, is adding in new functionality for Linux 3.19. First up, CephFS for Linux 3.19 adds support for inline data. Inline data makes the file-system quicker for accessing small files and is a feature already supported by Btrfs, EXT4, and other file-systems. Inline data support for Ceph has been a long time coming and is outlined further on this Ceph Wiki page.
Ceph in Linux 3.19 also has support for message signatures in libceph. Both message signatures and inline data support were written by Yan, Zheng.
Ceph in Linux 3.19 also has various bug-fixes and code clean-ups. More details via this pull request. The Ceph improvements come on top of many other additions to Linux 3.19 as what will be the first major kernel update of 2015.
