Fixed version (ground truth):

    final VolumeManager vMan=master.getVolumeManager();
    final FileAccessManager faMan=master.getFileAccessManager();
    validateContext(rq);
    final Path p=new Path(rqArgs.getPath());
    final VolumeInfo volume=vMan.getVolumeByName(p.getComp(0));
    final StorageManager sMan=vMan.getStorageManager(volume.getId());
    final PathResolver res=new PathResolver(sMan,p);
    if (res.getParentDir() == null)     throw new UserException(ErrNo.EEXIST,"String_Node_Str" + res.getFileName() + "String_Node_Str");
    faMan.checkSearchPermission(sMan,res,rq.getDetails().userId,rq.getDetails().superUser,rq.getDetails().groupIds);
    faMan.checkPermission(FileAccessManager.O_WRONLY,sMan,res.getParentDir(),res.getParentsParentId(),rq.getDetails().userId,rq.getDetails().superUser,rq.getDetails().groupIds);
    res.checkIfFileExistsAlready();
    AtomicDBUpdate update=sMan.createAtomicDBUpdate(master,rq);
    long fileId=sMan.getNextFileId();
    int time=(int)(TimeSync.getGlobalTime() / 1000);
    sMan.createDir(fileId,res.getParentDirId(),res.getFileName(),time,time,time,rq.getDetails().userId,rq.getDetails().groupIds.get(0),rqArgs.getMode(),0,update);
    sMan.setLastFileId(fileId,update);
    MRCHelper.updateFileTimes(res.getParentsParentId(),res.getParentDir(),false,true,true,sMan,update);
