Jump history updating and state equivalence checks are conceptually independent, so move push_jmp_history() out of is_state_visited(). Also make a decision whether to perform state equivalence checks or not one layer higher in do_check(), keeping is_state_visited() unconditionally performing state checks. push_jmp_history() should be performed after state checks. There is just one small non-uniformity. When is_state_visited() finds already validated equivalent state, it propagates precision marks to current state's parent chain. For this to work correctly, jump history has to be updated, so is_state_visited() is doing that internally. But if no equivalent verified state is found, jump history has to be updated in a newly cloned child state, so is_jmp_point() + push_jmp_history() is performed after is_state_visited() exited with zero result, which means "proceed with validation". This change has no functional changes. It's not strictly necessary, but feels right to decouple these two processes.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
