    Subject[PATCH v5 15/25] kernel-doc: bugfix - multi-line macros
    Date
    Prior to this patch the following code breaks:

    /**
    * multiline_example - this breaks kernel-doc
    */
    #define multiline_example( \
    myparam)

    Producing this error:

    Error(somefile.h:983): cannot understand prototype: 'multiline_example( \ '

    This patch fixes the issue by appending all lines ending in a blackslash
    (optionally followed by whitespace), removing the backslash and any
    whitespace after it prior to appending (just like the C pre-processor
    would).

    This fixes a break in kerel-doc introduced by the additions to rbtree.h.
