Author: Rémi Bernon <rbernon(a)codeweavers.com> Date: Sat Feb 11 09:43:30 2023 +0100 ntdll: Implement Low Fragmentation Heap frontend. This implements the reduced fragmentation from the heap frontend, by carving smaller blocks out of larger allocated blocks. The super block and each sub-block are all flagged with BLOCK_FLAG_LFH. The super-block (struct group) uses a standard struct block header, as well as a list entry to be linked in free list, and a free bit map to track free sub-blocks. Sub-blocks reference their super block through the base_offset, instead of the subheap, using the block size as radix. --- dlls/kernel32/tests/heap.c | 20 ++-- dlls/ntdll/heap.c | 276 +++++++++++++++++++++++++++++++++++++++++++-- 2 files changed, 277 insertions(+), 19 deletions(-)
