As you mentioned before, we don't need a 64bit value for
i_compr_blocks of inode.
Yup, I think atomic type is enough for both f2fs_inode_info.i_compr_blocks and
f2fs_sb_info.compr_blocks.

writepages() can be concurrently invoked for the same file by different

So, changing i_compr_blocks without protection is racy and we need to
protect it by changing it
