| Doc Text: |
Previously, the hfi1 driver called the preempt_disable() function to prevent migration on standard Red Hat Enterprise Linux and on Red Hat Enterprise Linux for Real Time. On Red Hat Enterprise Linux for Real Time with the realtime kernel (kernel-rt), calling preempt_disable() triggered a kernel panic. With this update, the kernel-rt code has been modified to use a realtime-specific function call to the preempt_disable_nort() function, which expands to the correct calls based on the kernel that is running. As a result, the hfi1 driver now works correctly on both Red Hat Enterprise Linux kernel and Red Hat Enterprise Linux for Real Time kernel-rt.
