Hi all. I rewrited lastlog_openseek function. Now is little more atomic when file operations on lastlog file happens.

John, This was my attempt to add symbol versioning to the library, letting us break ABI without breaking any existing callers. Unfortunately it doesn't work: - the new versioned symbols are marked local in libguestfs.so - the existing symbols should now have @GUESTFS_0.0 versions, but don't The documentation for this stuff is extremely thin, and I've got a bad case of

...later. This should greatly simplifies the code because it does not only reduce the complexity and amount of the existing code, but also reduces the amount of knowledge you need to have to read the code, without sacrificing performance of lld-generated files in practice.

This is a simpler patch series to add symbol versioning. I have pushed patches 1-3 upstream. Rich.

This rather more complex patch series adds symbol versioning (7/7 shows it in action). This works for me, tested by running old and new virt-inspector binaries against the new library. Rich.
