tools/mm: update the usage output to be more organized

2023-10-18T21:34:19Z

Organize the usage options alphabetically and improve the description of some options. Also separate the more complicated cull options from the single use compare options.

tools/mm: fix the default case for page_owner_sort

2023-10-18T21:34:19Z

With the additional commands and timestamps added to the tool, the default case (-t) has been broken. Now that the allocation timestamps are saved outside of the txt field, allow us to properly sort the data by number of times the record has been seen. Furthermore prevent the misuse of the commandline arguments so only one compare option can be used.

tools/mm: filter out timestamps for correct collation

2023-10-18T21:34:19Z

With the introduction of allocation timestamps being included in page_owner output, each record becomes unique due to the timestamp nanosecond granularity. Remove the check in add_list that tries to collate each record during processing as the memcmp() is just additional overhead at this point. Also keep the allocation timestamps, but allow collation to occur without consideration of the allocation timestamp except in the case were allocation timestamps are requested by the user (the -a option).

tools/mm: remove references to free_ts from page_owner_sort

2023-10-18T21:34:19Z

With the removal of free timestamps from page_owner output, we no longer need to handle this case or the "unreleased" case. Remove all references to both cases.

tools/mm: fix undefined reference to pthread_once

Merge tag 'slab-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

2023-04-25T20:00:41Z

Pull slab updates from Vlastimil Babka: "The main change is naturally the SLOB removal. Since its deprecation in 6.2 I've seen no complaints so hopefully SLUB_(TINY) works well for everyone and we can proceed. Besides the code cleanup, the main immediate benefit will be allowing kfree() family of function to work on kmem_cache_alloc() objects, which was incompatible with SLOB. This includes kfree_rcu() which had no kmem_cache_free_rcu() counterpart yet and now it shouldn't be necessary anymore. Besides that, there are several small code and comment improvements from Thomas, Thorsten and Vernon" * tag 'slab-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: mm/slab: document kfree() as allowed for kmem_cache_alloc() objects mm/slob: remove slob.c mm/slab: remove CONFIG_SLOB code from slab common code mm, pagemap: remove SLOB and SLQB from comments and documentation mm, page_flags: remove PG_slob_free mm/slob: remove CONFIG_SLOB mm/slub: fix help comment of SLUB_DEBUG mm: slub: make kobj_type structure constant slab: Adjust comment after refactoring of gfp.h

tools/mm/page_owner_sort.c: fix TGID output when cull=tg is used

When using cull option with 'tg' flag, the fprintf is using pid instead of tgid. It should use tgid instead.

tools/mm: allow users to provide additional cflags/ldflags

2023-02-03T06:33:24Z

Right now there is no way to provide additional cflags/ldflags when building tools/vm binaries. And using eg. make CFLAGS= will override the CFLAGS being set in the Makefile, making the build fail since it requires the include of the ../lib dir (for libapi). This change then allows you to specify: CFLAGS= LDFLAGS= make V=1 -C tools/vm And the options will be correctly appended as can be seen from the make output.

Rename tools/vm to tools/mm for being more consistent with the code and documentation directories, and won't be confused with virtual machines.
