My fault for taking the notes on paper instead of electronically in the first place. :-( This is my best reconstruction of some of the ext4 projects for 2014. Please let me know if I've forgotten anything. 1) Support for Shingled (SMR) Drives 2) Data block compression -- Lukas 3) reflink support --- Mingming block-level snapshot support Use case: (a) VM guest images which are mostly derived from the same common master image 4) Subvolume quotas (aka project quotas) -- Zheng 5) block improvements -- raid support / flash block size 6) Better support for non-rotating media Differences between thinp and flash? General problem: how do we measure improvements in the block allocator? Other more minor todo items: A) Finish integration of inline support in e2fsprogs B) Dioread nolock cleanup C) Extent status tree shrinker - Ted
