H A Dkernel-docdiff 654784284430bf2739985914b65e09c7c35a7273 Fri Oct 05 02:15:05 CEST 2012 Daniel Santos <daniel.santos@pobox.com> kernel-doc: bugfix - multi-line macros

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.
