malloc: move malloc_type_internal into malloc_type

2020-11-06T21:33:59Z

According to code comments the original motivation was to allow for malloc_type_internal changes without ABI breakage. This can be trivially accomplished by providing spare fields and versioning the struct, as implemented in the patch below. The upshots are one less memory indirection on each alloc and disappearance of mt_zone. Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D27104

memstat_kvm_uma: fix reading of uma_zone_domain structures

2020-08-28T19:50:40Z

Coverity flagged the scaling by sizeof(uzd). That is the type of the pointer, so the scaling was already done by pointer arithmetic. However, this was also passing a stack frame pointer to kvm_read, so it was doubly wrong. Move ZDOM_GET into the !_KERNEL section and use it in libmemstat.

Use per-domain locks for the bucket cache.

2020-02-19T18:48:46Z

This gives much better concurrency when there are a large number of cores per-domain and multiple domains. Avoid taking the lock entirely if it will not be productive. ROUNDROBIN domains will have mixed memory in each domain and will load balance to all domains. While here refactor the zone/domain separation and bucket limits to simplify callers.
