If you want to have a fully flexible interface, then we probably
should have a way to both get and set the flag.  And from there the
next step down the slippery slope would be to make this be a bit more
like a fcntl-style F_GETFL/F_SETFL style interface, so we can in the
future set and get other ext4-specific struct_file-specific flags.  :-)

I'll let you decide how far you want to go with this; I won't mind if
you keep it with the original KISS interface, but I also won't mind if
you want to create a somewhat more expansive interface.
