Patches 1 & 2 are about a fix needed to make zero-copy flush work.
The code that incremented the sendmsg counter ended up missing in
the last versions of the patchset, causing the flush to never
happen.
Patch 3 is about an improvement on flushing that improves
sending performance.
Patch 4 is about making zero-copy-send a migration capability,
instead of a migration parameter. Which actually makes more sense
and helps the implementation of the libvirt code.
Leonardo Bras (4):
QIOChannelSocket: Introduce assert and reduce ifdefs to improve
readability
QIOChannelSocket: Fix zero-copy send so socket flush works
migration: zero-copy flush only at the end of bitmap scanning
migration: Change zero_copy_send from migration parameter to migration
capability
