Hi, This patchset is to improve handling and reporting of memory errors on dirty pagecache. Patch 1 is to fix a messaging bug, and patch 2 is to temporarily undo the code which can happen the data lost. I think these two are obvious fixes so I want to push them to merge promptly. Patch 3 is for a new feature. The problem in error reporting (where AS_EIO we rely on to report the error to userspace is cleared once checked) is discussed when hwpoison core patches were reviewed, and we left it unfixed because it can be fixed with more generic solution which covers legacy EIO. But in my opinion, legacy EIO and hwpoison are different in how it can or should be handled (for example, as described in patch 3, we can recover from memory errors on dirty pagecache with overwriting.) So this patch only solves the problem of memory error reporting. My test for this patchset is available on: https://github.com/Naoya-Horiguchi/test_memory_error_on_dirty_pagecache.git Could you review or comment?
