They'll just be ignored for now, but you can do this to mark internal company procedures or just point out some special detail about the sign-off. +If you are a subsystem or branch maintainer, sometimes you need to slightly +modify patches you receive in order to merge them, because the code is not +exactly the same in your tree and the submitters'.

Rule (b) allows you to adjust +the code, but then it is very impolite to change one submitter's code and +make him endorse your bugs.

The scripts/kernel-doc perl script, some +SGML templates in Documentation/DocBook, and other tools understand +these conventions, and are used to extract this embedded documentation +into various documents. + +In order to provide good documentation of kernel functions and data +structures, please use the following conventions to format your +kernel-doc comments in Linux kernel source. + +We definitely need kernel-doc formatted documentation for functions +that are exported to loadable modules using EXPORT_SYMBOL. + +We also look to provide kernel-doc formatted documentation for +functions externally visible to other kernel files (not marked +"static"). + +We also recommend providing kernel-doc formatted documentation +for private (file "static") routines, for consistency of kernel +source code layout. But this is lower priority and at the +discretion of the MAINTAINER of that kernel source file. + +Data structures visible in kernel include files should also be +documented using kernel-doc formatted comments. + +The opening comment mark "/**" is reserved for kernel-doc comments. +Only comments so marked will be considered by the kernel-doc scripts, +and any comment so marked must be in kernel-doc format. Do not use +"/**" to be begin a comment block unless the comment block contains +kernel-doc formatted comments. The closing comment marker for +kernel-doc comments can be either "*/" or "**/". + +Kernel-doc comments should be placed just before the function +or data structure being described. + +Example kernel-doc function comment: + +/** + * foobar() - short function description of foobar + * @arg1: Describe the first argument to foobar. + * @arg2: Describe the second argument to foobar. + * One can provide multiple line descriptions + * for arguments. + * + * A longer description, with more discussion of the function foobar() + * that might be useful to those using or modifying it.
