waste the first pool if malloc happens to return a pool-aligned address. This means the number of pools per arena can now vary by 1. Unfortunately, the code counted up from 0 to a presumed constant number of pools. So changed the increasing "watermark" counter to a decreasing "nfreepools" counter instead, and fiddled various stuff accordingly. This also allowed getting rid of two more macros. Also changed the code to align the first address to a pool boundary instead of a page boundary. These are two parallel sets of macro #defines that happen to be identical now, but the page macros are in theory more restrictive (bigger), and there's simply no reason I can see that it wasn't aligning to the less restrictive pool size all along (the code only relies on pool alignment). Hmm. The "page size" macros aren't used for anything *except* defining the pool size macros, and the comments claim the latter isn't necessary. So this has the feel of a layer of indirection that doesn't serve a purpose; should probably get rid of the page macros now. |
