I think you're confusing the memory_failure() HWPoison path with some XFS internal checking. I don't think XFS has any HWPoison checking on its own. > As it is, there is no way for the filesytem to be notified about > such failures on active pages in buffers, so in reality we can't > reliably detect them so there is little point in trying to recover > from such errors. Well it works today if the page is in pagecache. memory-failure will just remove it transparently. In principle you can check for HWPoison manually yourself, but I'm not sure that is a good way to do it. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
