AH create may be called from interrpt context and driver has a special timeout (8 sec) for this command. This is to avoid soft lockups when the FW command takes more time. Driver returns -ETIMEOUT and fail create AH, without waiting for actual completion from firmware. When FW completion is received, use is_waiter_alive flag to avoid a regular completion path. If create_ah opcode is detected in completion path which does not have waiter alive, driver will fetch ah_id from successful firmware completion in the interrupt context and sends destroy_ah command for same ah_id. This special post is done in quick manner using helper function __send_message_no_waiter. timeout_send is only used for debugging purposes. If timeout_send value keeps incrementing, it indicates out of sync active ah counter between driver and firmware. This is a limitation but graceful handling is possible in future.

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.
