DevLsiLogicSCSI.cpp@ 71963

Last change on this file since 71963 was 71775, checked in by vboxsync, 7 years ago
Devices/Storage: Properly account for requests currently waiting for I/O memory when suspending/resuming to avoid hangs upon suspend (devices would not complete suspending because aiting requests would be marked as active but could not complete)
