The below commit disallows to set compression on empty created file which

It needs to check return value of f2fs_convert_inline_inode()?

I intended to catch that in the below checks?

But it may hide the real error number, e.g. -ENOMEM returned from
f2fs_convert_inline_inode()?

Thanks,



Thanks,
