mm, treewide: introduce NR_PAGE_ORDERS

2024-05-02T14:32:41Z

[ Upstream commit fd37721803c6e73619108f76ad2e12a9aa5fafaf ] NR_PAGE_ORDERS defines the number of page orders supported by the page allocator, ranging from 0 to MAX_ORDER, MAX_ORDER + 1 in total. NR_PAGE_ORDERS assists in defining arrays of page orders and allows for more natural iteration over them.

mm,thp: no space after colon in Mem-Info fields

2023-08-21T20:38:01Z

Patch series "mm,thp: fix sloppy text output". Three independent trivial patches, fixing sloppy text output which has annoyed me; but might risk surprising a parser, so any can be dropped. This patch (of 3): The SysRq-m or OOM Mem-Info dmesg showed (long lines containing) ... shmem:NkB shmem_thp: NkB shmem_pmdmapped: NkB anon_thp: NkB ... Delete the space after the colon after shmem_thp, shmem_pmdmapped, anon_thp: as the shmem example shows, no other fields have a space after the colon in this output.

mm: make show_free_areas() static

2023-08-18T17:12:02Z

All callers of show_free_areas() pass 0 and NULL, so we can directly use show_mem() instead of show_free_areas(0, NULL), which could make show_free_areas() a static function.

mm: page_alloc: collect mem statistic into show_mem.c

2023-06-09T23:25:22Z

Let's move show_mem.c from lib to mm, as it belongs memory subsystem, also split some memory statistic related functions from page_alloc.c to show_mem.c, and we cleanup some unneeded include. There is no functional change.
