[Qemu-devel] [PULL 01/15] migration: Use savevm_handlers instead of loadvm copy

[Juan Quintela]

There is no reason for having the loadvm_handlers at all.  There is
only one use, and we can use the savevm handlers.

We will remove the loadvm handlers on a following patch.

[Qemu-devel] [PULL 05/15] migration: shut src return path unconditionally

[Juan Quintela]

From: Peter Xu <peterx@redhat.com>

We were do the shutting off only for postcopy. Now we do this as long as
the source return path is there.

Moving the cleanup of from_src_file there too.

[Qemu-devel] [PULL 07/15] migration: Split qemu-file.h

[Juan Quintela]

Split the file into public and internal interfaces.  I have to rename
the external one because we can't have two include files with the same
name in the same directory.  Build system gets confused.  The only
exported functions are the ones that handle basic types.

[Juan Quintela]

Just for the functions exported from tls.c.  Notice that we can't
remove the migration/migration.h include from tls.c because it access
directly MigrationState for the tls params.
