Patches 1 and 2 introduce include/qemu/qarray.h which implements a deep auto free mechanism for arrays. Unlike GArray it does not require special macros, function calls or member dereferencing to access the individual array elements. So existing C-style array code can be retained with only very little changes.
In this initial version QArray only supports the concept of unique pointers, i.e. it does not support reference counting. The array (and all dynamically allocated memory of individual array elements) is auto freed once execution leaves the scope of the reference variable (unique pointer) associated with the array. Patches 3..5 are provided (e.g. as example) for 9p being the first user of this new QArray API. These particular patches 3..5 are rebased on my current 9p queue: https://github.com/cschoenebeck/qemu/commits/9p.next which are basically just the following two queued patches: https://github.com/cschoenebeck/qemu/commit/7772715d43908235940f5b7dec68d0458b1ccdf4 https://github.com/cschoenebeck/qemu/commit/838b55e392ea7d52e714fdba1db777f658aee2cc v1 -> v2: * Minor API comment changes [patch 1]. * Perform strong type check by using __builtin_types_compatible_p() instead of a weak check using sizeof() [patch 2].
