Patches 1 and 2 introduce include/qemu/qarray.h which implements a deep auto free mechanism for arrays. See commit log of patch 1 for a detailed explanation and motivation for introducing QArray.
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 v2 -> v3: * Refactor QArrayRef() -> QARRAY_REF() [patch 1], [patch 5]. * Commit log: Add more thorough explanation for the motivation of QArray, along with example for advantage over GArray [patch 1]. * Commit log: Add reason for using MIT license for qarray.h instead of the standard QEMU license GPLv2+ [patch 1]. * API doc comments: use 'size_t' type consistently in API doc example code [patch 1]. 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].
