Checking for all uses of concurrentTestAndClear(), we find that one result of IsoCellSet::remove() is also similarly incorrect. This patch fixes these errors, and also adds comments to document the intended return values of some relevant functions, as well as the reasoning behind how some of the return values are computed. 1927733 1 webkit-bug-importer 2023-01-23 23:58:22 -0800 <rdar://problem/104590361> 1927735 2 mark.lam 2023-01-24 00:07:18 -0800 Pull request: https://github.com/WebKit/WebKit/pull/9020 1927839 3 ews-feeder 2023-01-24 09:32:55 -0800 Committed 259287@main (3589dd6fe569): <https://commits.webkit.org/259287@main> Reviewed commits have been landed.
