HWPOISON: Enable .remove_error_page for migration aware file systems
Enable removing of corrupted pages through truncation for a bunch of file systems: ext*, xfs, gfs2, ocfs2, ntfs These should cover most server needs. I chose the set of migration aware file systems for this for now, assuming they have been especially audited. But in general it should be safe for all file systems on the data area that support read/write and truncate. Caveat: the hardware error handler does not take i_mutex for now before calling the truncate function. Is that ok?
