    fix mremap() vs. ioctx_kill() race · b2edffdd
    Al Viro authored
    teach ->mremap() method to return an error and have it fail for
    aio mappings in process of being killed
    Note that in case of ->mremap() failure we need to undo move_page_tables()
    we'd already done; we could call ->mremap() first, but then the failure of
    move_page_tables() would require undoing whatever _successful_ ->mremap()
    has done, which would be a lot more headache in general.
