From: Huajun Li <huajun...@intel.com> f2fs inode is so large, so small files can be stored directly in the inode, rather than just storing a single block address and storing the data elsewhere.
This patch set makes files less than ~3.4K store directly in inode block. a) space saving Test with kernel src(without repo data), it can save about 10% space with this patch set; b) performance Test this patch set with iozone, there is no obvious performance difference with the results of disabling this feature.
