commit dabe7fba461a3d1a48932004ac529d6609d94b38 Author: Justin Miller <[email protected]> AuthorDate: Fri Jul 14 16:17:27 2023 -0700 Commit: GitHub <[email protected]> CommitDate: Fri Jul 14 16:17:27 2023 -0700 [NTOS:IO] Implement IoConnectInterruptEx for fully specified interrupt types (#5416) Implement IoConnectInterruptEx() for CONNECT_FULLY_SPECIFIED. This gives ability to load various modern drivers that use IoConnectInterruptEx. Various drivers work after this change, such as serial.sys MS sample driver when compiled with the reactos tree and many more KMDF drivers from later Windows versions.
