    HWPOISON: Enable .remove_error_page for migration aware file systems · aa261f54
    Andi Kleen 提交于
    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?
