[Qemu-devel] [PATCH 0/3] WIP: Multifd compression support |

This series create compression code on top of multifd. It is still
WIP, but it is already:
- faster that current compression code
- it does the minimum amount of copies possible
- we allow support for other compression codes
- it pass the multifd test sent in my previous series
Test for existing code didn't work because code is too slow, I need to
make downtime 10 times bigger to make it to converge on my test
machine. This code works with same limits that multifd no-
ToDo:
- move printf's to traces
- move code to a struct instead of if (zlib) inside the main threads.
- improve error handling.
Please, review and coment.
Juan Quintela (3):
migration: Add multifd-compress parameter
multifd: compression support variables
multifd: Start of zlib compression code
