History
Matthew Dillon 24579ca1d7 The vnode pager (used when you do file-backed mmaps) must use the 
underlying physical sector size when aligning I/O transfer sizes.
    It cannot assume 512 bytes.

    We assume the underlying sector size is a power of 2.  If it isn't,
    mmap() will break badly anyway (in the same way mmap broke with NFS
    when NFS tried to cache piecemeal write ranges in buffers, before
    we enforced read-buffer-before-write-piecemeal for NFS).
