[Qemu-devel] [PATCH v4 00/10] tcg: Direct block chaining clean-up

[Sergey Fedorov]

From: Sergey Fedorov <address@hidden>

This series combines a set of patches which is meant to improve overall code
structure and readability of the direct block chaining mechanism. The other
point is to make a step towards thread safety of TB chainig.

The series' tree can be found in a public git repository [1].
