[Libguestfs] missing symbol

Hi, when pushing libguestfs 1.27.53 (1:1.27.53-1) through my build setup befor uploading it to Debian, I noticed that "guestfs_internal_lstatlist@Base", a symbol that has been there since 1.20, is now missing. This causes dpkg-gensymbols(1) whose job it is to compare the symbols from the newly-built libraries to the known state to fail. If the guestfs_internal_* functions are not considered to be part of the ABI (as explained in the 8664337cc39c8575ccb60abb8c6e30f92828ea51 commit message), why are they exported? Cheers, -Hilko
