There are a couple of kernel-doc comments in include/linux/mmzone.h but they have minor formatting issues that would cause kernel-doc warnings.

There are only two callers of __alloc_pages() so prune the thicket of alloc_page variants by combining the two functions together. Current callers of __alloc_pages() simply add an extra 'NULL' parameter and current callers of __alloc_pages_nodemask() call __alloc_pages() instead.

Collect the time when each allocation is freed, to help with memory analysis with kdump/ramdump. Add the timestamp also in the page_owner debugfs file and print it in dump_page(). Having another timestamp when we free the page helps for debugging page migration issues. For example both alloc and free timestamps being the same can gave hints that there is an issue with migrating memory, as opposed to a page just being dropped during migration.

The external module build shows the following warning if Module.symvers is missing in the kernel tree. WARNING: Symbol version dump "Module.symvers" is missing. Modules may not have dependencies or modversions. I think this is an important heads-up because the resulting modules may not work as expected. This happens when you did not build the entire kernel tree, for example, you might have prepared the minimal setups for external modules by 'make defconfig && make modules_preapre'. A problem is that 'make modules' creates Module.symvers even without vmlinux. In this case, that warning is suppressed since Module.symvers already exists in spite of its incomplete content. The incomplete (i.e. invalid) Module.symvers should not be created. This commit changes the second pass of modpost to dump symbols into modules-only.symvers. The final Module.symvers is created by concatenating vmlinux.symvers and modules-only.symvers if both exist. Module.symvers is supposed to collect symbols from both vmlinux and modules. It might be a bit confusing, and I am not quite sure if it is an official interface, but presumably it is difficult to rename it because some tools (e.g. kmod) parse it.

For simple text replacement, it is better to use a built-in function instead of sed if possible. You can save one process forking. I do not mean to replace all sed invocations because GNU Make itself does not support regular expression (unless you use guile). I just replaced simple ones. Signed-off-by: -

It can be quite useful to have ld emit a link map file, in order to debug or verify that special sections end up where they are supposed to, and to see what LD_DEAD_CODE_DATA_ELIMINATION manages to get rid of. The only reason I'm not just adding this unconditionally is that the .map file can be rather large (several MB), and that's a waste of space when one isn't interested in these things. Also make it depend on CONFIG_EXPERT. Signed-off-by:

Some parts of the documentation may lead the reader to think that the socket's own frames are always received when CAN_RAW_RECV_OWN_MSGS is enabled, but all frames are subject to filtering. As explained by Marc Kleine-Budde: On TX complete of a CAN frame it's pushed into the RX path of the networking stack, along with the information of the originating socket. Then the CAN frame is delivered into AF_CAN, where it is passed on to all registered receivers depending on filters. One receiver is the sending socket in CAN_RAW. Then in CAN_RAW the it is checked if the sending socket has RECV_OWN_MSGS enabled. Link: https://lore.kernel.org/r/20210420191212.42753-1-erik@flodin.me Signed-off-by:

pahole starts to use libbpf definitions and APIs since v1.13 after the commit 21507cd3e97b ("pahole: add libbpf as submodule under lib/bpf"). It works well with the git repository because the libbpf submodule will use "git submodule update --init --recursive" to update. Unfortunately, the default github release source code does not contain libbpf submodule source code and this will cause build issues, the tarball from https://git.kernel.org/pub/scm/devel/pahole/pahole.git/ is same with github, you can get the source tarball with corresponding libbpf submodule codes from https://fedorapeople.org/~acme/dwarves This change documents the above issues to give more information so that we can get the tarball from the right place, early discussion is here: https://lore.kernel.org/bpf/2de4aad5-fa9e-1c39-3c92-9bb9229d0966@loongson.cn/ Signed-off-by:Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by:
