- The irqbalance(1) man page did not contain documentation for the IRQBALANCE_BANNED_CPUS environment variable. This update adds the extensive documentation to this man page.
- The irqbalance daemon assigns each interrupt source in the system to a "class", which represents the type of the device (for example Networking, Storage or Media). Previously, irqbalance used the IRQ handler names from the /proc/interrupts file to decide the source class, which caused irqbalance to not recognize network interrupts correctly. As a consequence, systems that use NIC biosdevnames did not have their hardware interrupts distributed and pinned as expected. With this update, the device classification mechanism has been improved, which ensures a better interrupts distribution.
- Previously, the irqbalance init script started the irqbalance daemon with the "--foreground" option, which caused irqbalance to become unresponsive. With this update, the "--foreground" option has been removed from the init script and irqbalance now starts as expected.
