This rather complex set of patches allow non-optargs functions to gain optional arguments, while preserving source and binary backwards compatibility. The problem is that we cannot add an optional argument to an existing function. For example, we might want to add flags to the 'lvresize' API which currently has no optional arguments.

...did not co-work with MSVC. For example, following code I have: struct float4 { float x, y, z, w; }; struct float4x4 { float4 x, y, z, w; }; float4 fetch_vs( float4x4* mat ){ return mat->y; } Caller: // ... float4x4 mat; // Initialized float4 ret = fetch(mat); // fetch is JITed by LLVM float4 ret_vs = fetch_vs(mat) // ... Callee(LLVM): %vec4 = type { float, float, float, float } %mat44 = type { %vec4, %vec4, %vec4, %vec4 } define %vec4 @fetch( %mat44* %m ) { %matval = load %mat44* %m %v2 = extractvalue %mat44 %matval, 2 ret %vec4 %v2 } But if it is implemented by...

This patch isn't ready to go upstream. In fact, I think we might do a quick 1.30 release soon, and save this patch, and also the extensive changes proposed for the test suite[1], to after 1.30. Currently it is not safe to use the same handle from multiple threads, unless you implement your own mutexes. See: http://libguestfs.org/guestfs.3.html#multiple-handles-and-multiple-threads These

If we want to permit more than 255 drives to be added, then we will have to add the disks to the same virtio-scsi target using different unit (LUN) numbers. Unfortunately SCSI LUN enumeration in the Linux is not deterministic (eg. two disks with target=0, lun=[0,1] can be enumerated as /dev/sda or /dev/sdb randomly). Dealing with that will require some very complex device name translation on the
