| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the driver is still marked as maintained in MAINTAINERS, Comtrol does not really care about this ancient driver. They are still manufacturing serial devices, but those are controlled only by out-of-tree drivers. Comtrol didn't answer my pings, so this driver is apparently unmaintained. Aside from that, the driver was untouched for years, only whole-tree changes happened during the past years. The driver needs much more care, so drop it for now. If someone steps up to reintroduce it, they need to clean it up first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | You should use KCFLAGS to pass additional compiler flags from the command line. Using EXTRA_CFLAGS is wrong. EXTRA_CFLAGS is supposed to specify flags applied only to the current Makefile (and now deprecated in favor of ccflags-y). It is still used in arch/mips/kvm/Makefile (and possibly in external modules too). Passing EXTRA_CFLAGS from the command line overwrites it and breaks the build. I also fixed drivers/gpu/drm/tilcdc/Makefile because commit 816175dd1fd7 ("drivers/gpu/drm/tilcdc: Makefile, only -Werror when no -W* in EXTRA_CFLAGS") was based on the same misunderstanding.

For most of the kernel that's the wrong place, as the MAINTAINERS file shows. Adjust those sections to make them match current practice. This change also removes a contradiction with the recently added text Documentation/admin-guide/reporting-issues.rst, which is a reason for a 'this needs further discussion' warning note in there. The change is thus a prerequisite to remove that warning, nevertheless it is left for now to make sure people review the text's approach more carefully.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which was manufactured by the now-defunct ICP Vortex company, later acquired by Adaptec and superseded by the aacraid series of controllers. The driver itself would require a major overhaul before any modifications can be attempted, but seeing that it's unlikely to have any users left it should rather be removed completely.

I can safely say that this driver has no actual user because it was not working at all until: commit 8fdcabeac398 ("drivers/net/wan/x25_asy: Fix to make it work") The code in its current state still has problems: 1. The uses of "struct x25_asy" in x25_asy_unesc (when receiving) and in x25_asy_write_wakeup (when sending) are not protected by locks against x25_asy_change_mtu's changing of the transmitting/receiving buffers. Also, all "netif_running" checks in this driver are not protected by locks against the ndo_stop function. 2. The driver stops all TTY read/write when the netif is down. I think this is not right because this may cause the last outgoing frame before the netif goes down to be incompletely transmitted, and the first incoming frame after the netif goes up to be incompletely received. And there may also be other problems. I was planning to fix these problems but after recent discussions about deleting other old networking code, I think we may just delete this driver, too.

The goal is to avoid bloat of the namespace in the resulting kernel image. The script relies on object data, and only finds unused symbols for the configuration used to generate that object data. This results in a lot of false positive warnings such as symbols only used by a single architecture, or symbols which are used externally only under certain configurations. Running namespace.pl using allyesconfig, allmodconfig, and x86_64_defconfig yields the following results: * allmodconfig * 11122 unique symbol names with no external reference * 1194 symbols listed as multiply defined * 214 symbols it can't resolve * allyesconfig * 10997 unique symbol names with no external reference * 1194 symbols listed as multiply defined * 214 symbols it can't resolve * x86_64_defconfig * 5757 unique symbol names with no external reference * 528 symbols listed as multiply defined * 154 symbols it can't resolve The script also has no way to easily limit the scope of the checks to a given subset of the kernel, such as only checking for symbols defined within a module or subsystem. Discussion on public mailing lists seems to indicate that many view the tool output as suspect or not very useful (see discussions at [1] and [2] for further context). As described by Masahiro Yamada at [2], namespace.pl provides 3 types of checks: listing multiply defined symbols, resolving external symbols, and warnings about symbols with no reference. The first category of issues is easily caught by the linker as any set of multiply defined symbols should fail to link. The second category of issues is also caught by linking, as undefined symbols would cause issues. Even with modules, these types of issues where a module relies on an external symbol are caught by modpost. The remaining category of issues reported is the list of symbols with no external reference, and is the primary motivation of this script. However, it ought to be clear from the above examples that the output is difficult to sort through. Even allyesconfig has ~10000 entries. The current submit-checklist indicates that patches ought to go through namespacecheck and fix any new issues arising. But that itself presents problems. As described at [1], many cases of reports are due to configuration where a function is used externally by some configuration settings. Prominent maintainers appear to dislike changes modify code such that symbols become static based on CONFIG_* flags ([3], and [4]) One possible solution is to adjust the advice and indicate that we only care about the output of namespacecheck on allyesconfig or allmodconfig builds... However, given the discussion at [2], I suspect that few people are actively using this tool. It doesn't have a maintainer in the MAINTAINERS flie, and it produces so many warnings for unused symbols that it is difficult to use effectively. Thus, I propose we simply remove it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Git is fairly ubiquitous these days, and the additional information in this documentation for preparing patches without it is not especially relevant anymore and may serve to confuse new contributors. The git request-pull comments were also removed, given that it is not a tool well-suited to novice contributors, nor do maintainers especially appreciate receiving unexpected request-pulls from new contributors.
