  "message": "[roll] Roll fuchsia [starnix] Cache total memory mapping usage\n\nCache the total usage length inside the `Mappings` struct to optimize\n`get_total_usage` from O(N) to O(1). To keep the cached sum\nsynchronized, direct mutable access to the map via `DerefMut` is\nremoved. Mutation is now routed through new helper methods (`insert`,\n`remove`, `append_non_overlapping`) that keep the cached sum in sync.\n\nImproved gvisor_benchmarks: MapTouch*, MapUnmap*, ThreadStart*\nOriginal-Original-Bug: 484414845\nTest: starnix_core_tests\nOriginal-Original-Reviewed-on: https://fuchsia-review.googlesource.com/c/fuchsia/+/1614014\nOriginal-Original-Revision: 29c3dd10f1e795758381d714484aba6331fb0836\nGitOrigin-RevId: 3af5cf31e4c796d77a97d0da0730a2a0c0b66941\nChange-Id: Ifacb0b181f6c61e0adcfd1dbeb5245be1e5b952e\n",
