Bug ID: 171384
Summary: bmalloc scavenger should know what page classes are
allocating
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: bmalloc
Assignee: webkit-unassigned at lists.webkit.org
Reporter: msaboff at apple.com
CC: ggaren at apple.com
The scavenging process has one flag to indicate that bmalloc is allocating VM heap memory for any class. When we scavenge, we check this flag and wait for any allocations to complete. Instead we should keep a flag for every page size class and skip classes that are currently allocating and come back to them later.
