Enlarge pictureLinus Torvalds announced last evening the immediate availability of the 2.6.25 Linux kernel. This new release contains new technologies, some updated drivers and miscellaneous fixes:
"It's been long promised, but there it is now. Special thanks to Ingo who found and fixed a nasty-looking regression that turned out to not be a regression at all, but an old bug that just had not been triggering as reliably before. [..] So it's mostly one-liners, with some updates to drivers (net and usb) and to networking that are a bit larger (although a number of the driver updates are things like just new IDs etc)." said Linus Torvalds.
Let's have a look now at the most important technologies introduced in this release:
#Memory Resource Controller
#Real Time Group scheduling
#RCU Preemption support
#FIFO ticket spinlocks in x86
#Better process memory usage measurement
#timerfd() syscall
#SMACK, Simplified Mandatory Access Control
#Latencytop
#BRK and PIE executable randomization
#Controller area network (CAN) protocol support
#ACPI thermal regulation/WMI
#EXT4 update
#MN10300/AM33 architecture support
