All, I was experimenting with converting LPCTSTR strings to wide strings with something like this: // Converts a Ruby string to a LPWSTR LPCTSTR AllocWideLString(VALUE rbString){ char* str = STR2CSTR(rbString); int length = (strlen(str)+1) * sizeof(WCHAR); LPCTSTR lpStr = (LPCTSTR)malloc(length); MultiByteToWideChar( CP_ACP, 0, str, strlen(str)+1,

This line is missing. - int handle = ida_alloc_min(&vgdev->ctx_id_ida, 1, GFP_KERNEL); + int handle = ida_alloc(&vgdev->ctx_id_ida, GFP_KERNEL); It'll be there in v2 ;-)

I noticed you were using IDRs where you could be using the more efficient IDAs, then while fixing that I noticed the lack of error handling, and I decided to follow that up with an efficiency improvement. There's probably a v2 of this to follow because I couldn't figure out how to properly handle one of the error cases ... see the comment embedded in one of the patches. Matthew Wilcox
