Linus Torvalds d0b51bfb23 Revert "mm: shmem: don't truncate page if memory failure happens" ... This reverts commit b9d02f1bdd. The error handling of that patch was fundamentally broken, and it needs to be entirely re-done. For example, in shmem_write_begin() it would call shmem_getpage(), then ignore the error return from that, and look at the page pointer contents instead. And in shmem_read_mapping_page_gfp(), the patch tested PageHWPoison() on a page pointer that two lines earlier had potentially been set as an error pointer. These issues could be individually fixed, but when it has this many issues, I'm just reverting it instead of waiting for fixes.
