There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.

History

Linus Torvalds a49468240e Modules changes for v6.10-rc1 Finally something fun. Mike Rapoport does some cleanup to allow us to take out module_alloc() out of modules into a new paint shedded execmem_alloc() and execmem_free() so to make emphasis these helpers are actually used outside of modules. It starts with a no-functional changes API rename / placeholders to then allow architectures to define their requirements into a new shiny struct execmem_info with ranges, and requirements for those ranges. Archs now can intitialize this execmem_info as the last part of mm_core_init() if they have to diverge from the norm. Each range is a known type clearly articulated and spelled out in enum execmem_type. Although a lot of this is major cleanup and prep work for future enhancements an immediate clear gain is we get to enable KPROBES without MODULES now. That is ultimately what motiviated to pick this work up again, now with smaller goal as concrete stepping stone. This has been sitting on linux-next for a little less than a month, a few issues were found already and fixed, in particular an odd mips boot issue. Arch folks reviewed the code too. This is ready for wider exposure and testing. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmZDHfMSHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinfIwP/iFsr89v9BjWdRTqzufuHwjOxvFymWxU BbEpOppRny3CckDU9ag9hLIlUaSL1Bg56Zb+znzp5stKOoiQYMDBvjSYdfybPxW2 mRS6SClMF1ubWbzdysdp5Ld9u8T0MQPCLX+P2pKhZRGi0wjkBf5WEkTje+muJKI3 4vYkXS7bNhuTwRQ+EGfze4+AeleGdQJKDWFY00TW9mZTTBADjfHyYU5o0m9ijf5l 3V/weUznODvjVJStbIF7wEQ845Ae02LN1zXfsloIOuBMhcMju+x8IjPgPbD0KhX2 yA48q7mVWkirYp0L5GSQchtqV1GBiP0NK1xXWEpyx6EqQZ4RJCsQhlhjijoExYBR ylP4bqiGVuE3IN075X0OzGCnmOStuzwssfDmug0sMAZH/MvmOQ21WzZdet2nLMas wwJArHqZsBI9BnBlvH9ZM4Y9f1zC7iR1wULaNGwXLPx34X9PIch8Yk+RElP1kMFQ +YrjOuWPjl63pmSkrkk+Pe2eesMPcPB41M6Q2iCjDlp0iBp63LIx2XISUbTf0ljM EsI4ZQseYpx+BmC7AuQfmXvEOjuXII9z072/artVWcB2u/87ixIprnqZVhcs/spy 73DnXB4ufor2PCCC5Xrb/6kT6G+PzF3VwTbHQ1D+fYZ5n2qdyG+LKxgXbtxsRVTp oUg+Z/AJaCMt =Nsg4 -----END PGP SIGNATURE----- Merge tag 'modules-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull modules updates from Luis Chamberlain: "Finally something fun.
