  • 3476f114a   nfs: fix a minor do_div portability issue ... Browse Code »

    This change modifies filelayout_get_dense_offset() to use the functions
    in math64.h and thus avoid a 32-bit platform compile error trying to
    use do_div() on an s64 type.

    Some files were using the complete module.h infrastructure without
    actually including the header at all. Fix them up in advance so
    once the implicit presence is removed, we won't get failures like this:

  • 2bea038c5   pnfs: write: Set mds_offset in the generic layer - it is needed by all LDs ... Browse Code »

    In current pnfs tree, all the layouts set mds_offset in their
    .write_pagelist member.
    mds_offset is only used by generic layer and should be handled by it.

    This patch is for upstream. It is needed in this -rc series to fix a
    bug in objects layout_commit.

    I'll send patches for objects and blocks to be
    squashed into current pnfs tree.

    TODO: It looks like the read path needs the same patch.

  • a8a4ae3a8   NFSv41: Resend on NFS4ERR_RETRY_UNCACHED_REP ... Browse Code »

    Free the slot and resend the RPC with new session .

    For nfs4_async_handle_error, return -EAGAIN and set the task->tk_status to 0
    to restart the async rpc in the rpc_restart_call_prepare state which resets
    the slot.

    For nfs4_handle_exception, retrying a call that uses nfs4_call_sync will
    reset the slot via nfs41_call_sync_prepare.

    For open/close/lock/locku/delegreturn/layoutcommit/unlink/rename/write
    cachethis is true, so these operations will not trigger an
    NFS4ERR_RETRY_UNCACHED_REP.

    The filelayout driver sends LAYOUTCOMMIT only when COMMIT goes to
    the data server (as opposed to the MDS) and the data server WRITE
    is not NFS_FILE_SYNC.

    Only whole file layout support means that there is only one IOMODE_RW layout
    segment.

    Allows the pnfs filelayout driver to write to the data servers.

    Note that COMMIT to data servers will be implemented in a future
    patch. To avoid improper behavior, for the moment any WRITE to a data
    server that would also require a COMMIT to the data server is sent
    NFS_FILE_SYNC.

    If a data server is unavailable, go through MDS.

    Mark the deviceid containing the data server as a negative cache entry.
    Do not try to connect to any data server on a deviceid marked as a negative
    cache entry. Mark any layout that tries to use the marked deviceid as failed.

    Inodes with a layout marked as fails will not use the layout for I/O, and will
    not perform any more layoutgets.
    Inodes without a layout will still do layoutget, but the layout will get
    marked immediately.
