    xfs: limit specualtive delalloc to maxioffset · 3ed9116e

    Speculative delayed allocation beyond EOF near the maximum supported
    file offset can result in creating delalloc extents beyond
    mp->m_maxioffset (8EB). These can never be trimmed during
    xfs_free_eof_blocks() because they are beyond mp->m_maxioffset, and
    that results in assert failures in xfs_fs_destroy_inode() due to
    delalloc blocks still being present. xfstests 071 exposes this
    problem.
    
    Limit speculative delalloc to mp->m_maxioffset to avoid this
    problem.
