From bb44ad39c886401e1ffe0876565f8b3fcea64e9d Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Wed, 15 Oct 2008 22:02:34 -0700 Subject: [PATCH] checkpatch: trailing statements ensure we report the end of the line When reporting some complex trailing statements we report only the starting line of the error, that tends to imply the shown line is in error and confuse the reader. As we do know where the actual error is report that line too with an appropriate gap marker where applicable. #ERROR: trailing statements should be on next line #1: FILE: Z202.c:1: + for (pbh = page_buffers(bh->b_page); pbh != bh; + pbh = pbh->b_this_page, key++); #ERROR: trailing statements should be on next line #4: FILE: Z202.c:4: + for (pbh = page_buffers(bh->b_page); [...] + pbh = pbh->b_this_page, key++); Signed-off-by: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- scripts/checkpatch.pl | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index a675f067b572..2c1afba57580 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -2001,7 +2001,16 @@ sub process { if (length($c) && $s !~ /^\s*{?\s*\\*\s*$/ && $c !~ /}\s*while\s*/) { - ERROR("trailing statements should be on next line\n" . $herecurr); + # Find out how long the conditional actually is. + my @newlines = ($c =~ /\n/gs); + my $cond_lines = 1 + $#newlines; + + my $stat_real = raw_line($linenr, $cond_lines); + if (defined($stat_real) && $cond_lines > 1) { + $stat_real = "[...]\n$stat_real"; + } + + ERROR("trailing statements should be on next line\n" . $herecurr . $stat_real); } } -- 2.20.1
