Not quite sure tho, compressed blocks are logi

Hi Jaegeuk,

inode.i_blocks counts based on 512byte sector, we need to convert
to 4kb sized block count before comparing to i_compr_blocks.
In addition, add to print message when sanity check on inode
compression configs failed.

If regular inode has no compressed cluster, allow using 'chattr -c'
to remove its compress flag, recovering it to a non-compressed file.

Compressed cluster can be generated during dirty data writeback,
if there is dirty pages on compressed inode, it needs to disable
converting compressed inode to non-compressed one.

Generally, data shows better continuity in warm data area as its
default allocation direction is right, in order to enhance
sequential read/write performance of compress inode, let's force
compress data into warm area.

stat_inc_compr_inode() needs to check FI_COMPRESSED_FILE flag, so
in f2fs_disable_compressed_file(), we should call stat_dec_compr_inode()
before clearing FI_COMPRESSED_FILE flag.

Use LZ4 as default compression algorithm, as compared to LZO, it shows
almost the same compression ratio and much better decompression speed.
