mm/mm_init.c: clean code. Use BUILD_BUG_ON when comparing compile time constant

2020-04-07T17:43:41Z

MAX_ZONELISTS is a compile time constant, so it should be compared using BUILD_BUG_ON not BUG_ON.

mm: convert totalram_pages and totalhigh_pages variables to atomic

2018-12-28T20:11:47Z

totalram_pages and totalhigh_pages are made static inline function. Main motivation was that managed_page_count_lock handling was complicating things. It was discussed in length here, https://lore.kernel.org/patchwork/patch/995739/#1181785 So it seemes better to remove the lock and convert variables to atomic, with preventing poteintial store-to-read tearing as a bonus.

mm: access zone->node via zone_to_nid() and zone_set_nid()

2018-08-22T17:52:45Z

zone->node is configured only when CONFIG_NUMA=y, so it is a good idea to have inline functions to access this field in order to avoid ifdef's in c files.

mm: convert printk(KERN_ to pr_

2016-03-17T22:09:34Z

Most of the mm subsystem uses pr_ so make it consistent. Miscellanea: - Realign arguments - Add missing newline to format - kmemleak-test.c has a "kmemleak: " prefix added to the "Kmemleak testing" logging message via pr_fmt Signed-off-by: Joe Perches Acked-by: Tejun Heo [percpu] Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mm: meminit: remove mminit_verify_page_links

2015-07-01T02:44:56Z

mminit_verify_page_links() is an extremely paranoid check that was introduced when memory initialisation was being heavily reworked. Profiles indicated that up to 10% of parallel memory initialisation was spent on checking this for every page. The cost could be reduced but in practice this check only found problems very early during the initialisation rewrite and has found nothing since. This patch removes an expensive unnecessary check.

mm: meminit: initialise remaining struct pages in parallel with kswapd

2015-07-01T02:44:56Z

Only a subset of struct pages are initialised at the moment. When this patch is applied kswapd initialise the remaining struct pages in parallel. This should boot faster by spreading the work to multiple CPUs and initialising data that is local to the CPU. The user-visible effect on large machines is that free memory will appear to rapidly increase early in the lifetime of the system until kswapd reports that all memory is initialised in the kernel log. Once initialised there should be no other user-visibile effects.

mm/mm_init.c: mark mminit_loglevel __meminitdata

2015-02-13T02:54:11Z

mminit_loglevel is only referenced from __init and __meminit functions, so we can mark it __meminitdata.

mm/mm_init.c: park mminit_verify_zonelist as __init

2015-02-13T02:54:11Z

The only caller of mminit_verify_zonelist is build_all_zonelists_init, which is annotated with __init, so it should be safe to also mark the former as __init, saving ~400 bytes of .text.

mm: bring back /sys/kernel/mm

2014-01-28T05:02:39Z

Commit da29bd36224b ("mm/mm_init.c: make creation of the mm_kobj happen earlier than device_initcall") changed to pure_initcall(mm_sysfs_init). That's too early: mm_sysfs_init() depends on core_initcall(ksysfs_init) to have made the kernel_kobj directory "kernel" in which to create "mm". Make it postcore_initcall(mm_sysfs_init). We could use core_initcall(), and depend upon Makefile link order kernel/ mm/ fs/ ipc/ security/ ... as core_initcall(debugfs_init) and core_initcall(securityfs_init) do; but better not.
