dm vdo: update vdo_allocate_extended to take a field name, no types

2026-03-02T16:03:18+00:00

All of VDO's "extended" allocations use a flexible array field at the end of the allocated structure. We can infer the struct type from the supplied pointer. Replacing the array field type with the field name lets us use struct_size from overflow.h to compute the size instead of the local __vdo_do_allocation version. One allocation of bio structures doesn't conform to this pattern, since the removal of bi_inline_vecs; directly compute the total size for that case.

Lists are the new rings, so update all remaining references to rings to talk about lists. Signed-off-by: Sweet Tea Dorminy Signed-off-by: Matthew Sakai Signed-off-by: Mikulas Patocka

dm vdo permassert: audit all of ASSERT to test for VDO_SUCCESS

2024-03-04T20:07:56+00:00

Also rename ASSERT to VDO_ASSERT and ASSERT_LOG_ONLY to VDO_ASSERT_LOG_ONLY. But re-introduce ASSERT and ASSERT_LOG_ONLY as a placeholder for the benefit of dm-vdo/indexer. Signed-off-by: Mike Snitzer Signed-off-by: Matthew Sakai

dm vdo: add basic hash map data structures

2024-02-20T18:43:13+00:00

This patch adds two hash maps, one keyed by integers, the other by pointers, and also a priority heap. The integer map is used for locking of logical and physical addresses. The pointer map is used for managing concurrent writes of the same data, ensuring that those writes are deduplicated. The priority heap is used to minimize the search time for free blocks.
