Rémi Bernon : ntoskrnl.exe/tests: Add some pending / remove tests.
Module: wine Branch: master Commit: 19d1375bce83bfeca08cab2c869b325304507ace URL: https://source.winehq.org/git/wine.git/?a=commit;h=19d1375bce83bfeca08cab2c8... Author: Rémi Bernon <rbernon(a)codeweavers.com> Date: Wed Jun 30 10:19:07 2021 +0200 ntoskrnl.exe/tests: Add some pending / remove tests. This shows that removing a device should send IRP_MN_SURPRISE_REMOVAL only, and that it's still possible to use DeviceIoControl on already opened handles. IRP_MN_REMOVE_DEVICE should only be sent when all then opened handles are closed.
