MountTable.hpp:80: "&" when "&&" may be intended ?

[dcb]

gcc compiler can be made to say:

src/main/../Model/MountTable.hpp:80:41: warning: suggest parentheses around comparison in operand of '|' [-Wparentheses]

Source code is

        return this->fileSystem == "aufs" | this->fileSystem == "overlayfs";

Maybe better code:

        return this->fileSystem == "aufs" || this->fileSystem == "overlayfs";
