Module: wine Branch: master Commit: 1445ae79e69ad684af0127d4cfbbe9715a687eec URL: https://source.winehq.org/git/wine.git/?a=commit;h=1445ae79e69ad684af0127d4c...

kernelbase: Also pass CreateFile2 file flags to CreateFileW.
Instead of just attributes.
Otherwise we may miss important flags like FILE_FLAG_OVERLAPPED and open the file for synchronous I/O, causing a deadlock in Flight Simulator.
