Re: [PATCH v2 01/16] mm: Add AOP_UPDATED_PAGE return value

[Christoph Hellwig]

Don't we also need to handle the new return value in a few other places
like cachefiles_read_reissue swap_readpage?  Maybe those don't get
called on the currently converted instances, but just leaving them
without handling AOP_UPDATED_PAGE seems like a time bomb.
