Juan Quintela	e1fde0e038	migration: Move rate_limit_max and rate_limit_used to migration_stats These way we can make them atomic and use this functions from any place. I also moved all functions that use rate_limit to migration-stats. Functions got renamed, they are not qemu_file anymore. qemu_file_rate_limit -> migration_rate_exceeded qemu_file_set_rate_limit -> migration_rate_set qemu_file_get_rate_limit -> migration_rate_get qemu_file_reset_rate_limit -> migration_rate_reset qemu_file_acct_rate_limit -> migration_rate_account.

Paolo Bonzini	394b9407e4	migration: mark mixed functions that can suspend There should be no paths from a coroutine_fn to aio_poll, however in practice coroutine_mixed_fn will call aio_poll in the !qemu_in_coroutine() path. By marking mixed functions, we can track accurately the call paths that execute entirely in coroutine context, and find more missing coroutine_fn markers. This results in more accurate checks that coroutine code does not end up blocking. If the marking were extended transitively to all functions that call these ones, static analysis could be done much more efficiently. However, this is a start and makes it possible to use vrc's path-based searches to find potential bugs where coroutine_fns call blocking functions.

Markus Armbruster	58ea30f514	Clean up header guards that don't match their file name Header guard symbols should match their file name to make guard collisions less likely. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

Marc-André Lureau	d890344166	slirp: use libslirp migration code slirp migration code uses QEMU vmstate so far, when building WITH_QEMU. Introduce slirp_state_{load,save,version}() functions to move the state saving handling to libslirp side. So far, the bitstream compatibility should remain equal with current QEMU, as this is effectively using the same code, with the same format etc. When libslirp is made standalone, we will need some mechanism to ensure bitstream compatibility regardless of the libslirp version installed. See the FIXME note in the code.

Juan Quintela	08a0aee15c	migration: Split qemu-file.h 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. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>	9 years ago
