[f2fs-dev 0/5] f2fs: Enable f2fs support inline data

From: Huajun Li
Date: Fri Oct 25 2013 - 12:07:40 EST

From: Huajun Li <huajun.li@xxxxxxxxx>

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.

Huajun Li (5):
f2fs: Add flags and helpers to support inline data
f2fs: Add a new mount option: inline_data
f2fs: Add a new function: f2fs_reserve_block()
f2fs: Key functions to handle inline data
f2fs: Handle inline data read and write
