smc_lgr_cleanup_early() schedules the free worker with delay. DMB unregistering occurs in this delayed worker increasing the risk to reach the SMCD SBA limit without need. Terminate the linkgroup immediately, since termination means early DMB unregistering. For SMCD the global smc_server_lgr_pending lock is given up early. A linkgroup to be given up with smc_lgr_cleanup_early() may already contain more than one connection. Using __smc_lgr_terminate() in smc_lgr_cleanup_early() covers this. And consolidate smc_ism_put_vlan() and smc_put_device() into smc_lgr_free() only.

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.
