    fs/vfs: inherit ownership in pseudofile_create
    
    Initialize i_owner and i_group from the creating task's
    effective uid/gid when a pseudo-file is created via O_CREAT.
    
    This aligns pseudo-file ownership with the creator's
    effective credentials instead of leaving new files
    root-owned by default.
