From: Robin Dong <redacted> Hi, This patch series change ee_block and ee_len (of extent) 's unit from "block" to "cluster", since it could reduce the space occupied by meta data. This patch series should be used after Ted's bigalloc-patchs and it now can't support: 1. delay allocation 2. 1k/2k blocksize
