The get_unit_name() function crafts a string based on the device name and the device unit number. It then stores this in a static variable. This has concurrency issues as can be seen with this log: hfi1 0000:02:00.0: hfi1_1: read_idle_message: read idle message 0x203 hfi1 0000:01:00.0: hfi1_1: read_idle_message: read idle message 0x203 The PCI device ID (0000:02:00.0 vs. 0000:01:00.0) is correct for the message, but the device string hfi1_1 is incorrect (it should be hfi1_0 for the second log message). Remove get_unit_name() function. Instead, use the rvt accessor rvt_get_ibdev_name() to get the IB name string. Clean up any hfi1_early_xx calls that can now use the new path. QIB has the same (qib_get_unit_name()) issue. Updating as necessary. Remove qib_get_unit_name() function. Update log message that has redundant device name.

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.
