The existing fcloop driver expects the target side upcalls to the transport to context switch, thus the calls into the nvmet layer are not done in the calling context of the host/initiator down calls. The xxx_IN_ISR feature flags are used to select this logic. The xxx_IN_ISR feature flags should go away in the nvmet_fc transport as no other lldd utilizes them. Both Broadcom and Cavium lldds have their own non-ISR deferred handlers thus the nvmet calls can be made directly. This patch converts the paths that make the target upcalls (command receive, abort receive) such that they schedule a work item rather than expecting the transport to schedule the work item. The patch also cleans up the following: - The completion path from target to host scheduled a host work element called "work". Rename it "tio_done_work" for code clarity. - The abort io path called a iniwork item to call the host side io done. This is no longer needed as the abort routine can make the same call.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
