Revert "[PartitionAlloc] Don't sort already-sorted freelists." This reverts commit e594ceb5413566356e46fb1793383fc34f46a6ba. Reason for revert: Newly introduced test failing on some configs. Original change's description: > [PartitionAlloc] Don't sort already-sorted freelists. > > If a slot span hasn't been touched since the last sort, there is no need > to sort it again. This is intended to reduce the CPU cost of freelist > sorting. > > This is motivated by stack-sampled metrics showing that the cost of > freelist sorting is non-trivial in the browser process. It also allows > to track whether a slot span is "idle", which may be used to decommit > part of the freelist if possible. > > Bug: 998048 > Change-Id: I06cb59e1dffdec23fc1869ee8bd8e6dba70c6bd6 > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3259733 > Reviewed-by: Bartek Nowierski <bartekn@chromium.org> > Commit-Queue: Benoit L <lizeb@chromium.org> > Cr-Commit-Position: refs/heads/main@{#938209} Bug: 998048 Change-Id: I36aee865bc7589a004901bcf1aea109cf8995684 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3259638 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Mohamed Amir Yosef <mamir@chromium.org> Commit-Queue: Benoit L <lizeb@chromium.org> Cr-Commit-Position: refs/heads/main@{#938227}
Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone
! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
