iscsit_close_session() uses in_interrupt() to decide if it needs to check the return value of iscsit_check_session_usage_count() if it was not able to sleep. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. iscsit_close_session() has two callers: - iscsit_handle_time2retain_timeout() A timer_list callback. - iscsit_close_connection() Runs in preemptible context, acquires a mutex. Add an argument to iscsit_close_session() indicating if sleeping is possible.

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.
