    ioctx_alloc(): remove pointless check · 08397acd
    Al Viro 提交于
    Way, way back kiocb used to be picked from arrays, so ioctx_alloc()
    checked for multiplication overflow when calculating the size of
    such array.  By the time fs/aio.c went into the tree (in 2002) they
    were already allocated one-by-one by kmem_cache_alloc(), so that
    check had already become pointless.  Let's bury it...
