[Xen-devel] Features and bug fixes that went in Linux 3.1
Hey,
3.1 is going to be released shortly, I hope. The 3.1 release saw:
- Xen-pciback module included in.
- Support for udev to autoload Xen backend modules.
- Blkback decreasing latency on I/Os.
- VGA dom0 text support (which also went in 3.0.4)
- Frontswap support and self-ballooning (for tmem)
- Replacing Xen debugfs with a general tracing facility
- PVonHVM saw PV keyboard driver being enabled and PV spinlocks
disabled (enabling it introduced a serious bug that will be fixed
in 3.3)
- Fixing some nasty bugs that existed since 2.6.27 and 2.6.37!
- Bug-fixes!
