[PATCH 0/2] MR6841: wow64: Support running a BT module provided suspend routine.
Suspension in JITs cannot easily be handled on the unix side, so allow BT modules to provide their own suspend helper. This purely supports local thread suspension currently. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6841

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=149741 Your paranoid android. === debian11b (64 bit WoW report) === user32: input.c:4305: Test succeeded inside todo block: button_down_hwnd_todo 1: got MSG_TEST_WIN hwnd 00000000004200EE, msg WM_LBUTTONDOWN, wparam 0x1, lparam 0x320032 win.c:4070: Test failed: Expected active window 00000000024D0136, got 0000000000000000. win.c:4071: Test failed: Expected focus window 00000000024D0136, got 0000000000000000.
