My personal expectation would be for that second line to be indented
with a tab. But I might be convinced otherwise?

There are also other preprocessor directives on which the 2.6.36
checkpatch complains, e.g.:

#warning A very long warning message that takes multiple lines and of which\
the second line starts with a space.

Why does the 2.6.36 checkpatch complain that the second line should
start with a tab instead of a space (which would make the message
really ugly) ?
