This is a reland of commit a19316d9 - Revert malloc_usable_size() changes temporarily to land them in isolation. - Add cosmetics from https://crrev.com/c/3827876 Original change's description: > [heap] Rework Worklist base type > > Worklist uses a singly-linked list of segments to hold entries. > Segment size was based on a compile-time constant but already stored > in the segment itself. > > Rework the segments to query `malloc_usable_size()` on allocation and > adjust the capacity properly. For PartitionAlloc, it turns out that > there's ~20% more capacity available for the 64-element segments. > > This slows down actual allocation of the segments with the upside of > improving utilization and requiring 20% less segments. > > Change-Id: Ib8595c3fb9fb75b02e4022f6c525bb59a2df7ab7 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3826047 > Commit-Queue: Anton Bikineev <bikineev@chromium.org> > Commit-Queue: Michael Lippautz <mlippautz@chromium.org> > Reviewed-by: Anton Bikineev <bikineev@chromium.org> > Cr-Commit-Position: refs/heads/main@{#82432} Change-Id: Ic8c5257cfe3c347b11eea5c513ca7f62e09f637f Bug: v8:13193 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3829475Reviewed-by: Anton Bikineev <bikineev@chromium.org> Commit-Queue: Michael Lippautz <mlippautz@chromium.org> Cr-Commit-Position: refs/heads/main@{#82493}
