[PATCH v1] checkpatch: test missing initial blank line in block comment

Show all headers | View raw

Hi checkpatch maintainers,

here is a patch tentative to raise a warning when multiple line block comments
are not starting with empty blank comment:

Warn when block comments are not starting with blank comment:
    /* multiple lines
     * block comment,
     * => warning
     */

    /*
     * multiple lines
     * block comment,
     * => no warning
     */

Exception made for networking files where rule is the
exact opposite.


* sample output:

$ scripts/checkpatch.pl -f drivers/media/v4l2-core/* | grep empty -A2
WARNING: Block comments starts with an empty /*
#393: FILE: drivers/media/v4l2-core/v4l2-compat-ioctl32.c:393:
+	/* For MMAP, driver might've set up the offset, so copy it back.

WARNING: Block comments starts with an empty /*

+	/* The MPEG controls are applicable to all codec controls

+	   the last element in the list has a lower ID.
[...]


* sample output in drivers/net/ (non-regression check):

$ scripts/checkpatch.pl -f drivers/net/*/* | grep empty -A2
