  • 235c362bd   UBIFS: extend debug/message capabilities ... Browse Code »

    In the case where we have more than one volumes on different UBI
    devices, it may be not that easy to tell which volume prints the
    messages. Add ubi number and volume id in ubifs_msg/warn/error
    to help debug. These two values are passed by struct ubifs_info.

    For those where ubifs_info is not initialized yet, ubifs_* is
    replaced by pr_*. For those where ubifs_info is not avaliable,
    ubifs_info is passed to the calling function as a const parameter.

    The output looks like,

  • 3668b70fc   UBIFS: print less ... Browse Code »

    UBIFS currently prints a lot of information when it mounts a volume, which
    bothers some people. Make it less chatty - print only important information
    by default.

    Get rid of 'dbg_msg()' macro completely.

  • a6aae4dd0   UBIFS: get rid of dbg_err ... Browse Code »

    This patch removes the 'dbg_err()' macro and we now use 'ubifs_err()' instead.
    The idea of 'dbg_err()' was to compile out some error message to make the
    binary a bit smaller - but I think it was a bad idea.

  • edf6be245   UBIFS: rename dumping functions ... Browse Code »

    This commit re-names all functions which dump something from "dbg_dump_*()" to
    "ubifs_dump_*()". This is done for consistency with UBI and because this way it
    will be more logical once we remove the debugging sompilation option.

    44

    Before commit 56e46742e846e4de167dde0e1e1071ace1c882a5 we have had locking
    around all printing macros and we could use static buffers for creating
    key strings and printing them. However, now we do not have that locking and
    we cannot use static buffers. This commit removes the old DBGKEY() macros
    and introduces few new helper macros for printing debugging messages plus
    a key at the end. Thankfully, all the messages are already structures in
    a way that the key is printed in the end.
