As some cases\nthat use the meta inode for GC, there are some race issues between a\nforeground thread and GC thread.\n\nTo handle them, we need to take care when to invalidate and wait\nwriteback of GC pages in COW files as the case of using the meta inode.\nAlso, a pointer from the COW inode to the original inode is required to\ncheck the state of original pages.\n\nFor the former, we can solve the problem by using the meta inode for GC\nof COW files. Then let's get a page from the original inode in\nmove_data_block when GCing the COW file to avoid race condition.\n\nFixes: 3db1de0e582c (\"f2fs: change the current atomic write way\")\nCc:
