This patch allows expired client with lock state to be in COURTESY state. Lock conflict with COURTESY client is resolved by the fs/lock code using the lm_lock_expirable and lm_expire_lock callback in the struct lock_manager_operations. If conflict client is in COURTESY state, set it to EXPIRABLE and schedule the laundromat to run immediately to expire the client. The callback lm_expire_lock waits for the laundromat to flush its work queue before returning to caller. Reviewed-by: J.

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.
