2.6.19 Linux Kernel Released

diegocgteleline.es writes, "After two months, Linux 2.6.19 has been released. It includes the clustering GFS2 filesystem, Ecryptfs, the first developer-oriented version of EXT4, support for the Atmel AVR32 architecture, sleepable RCU, improvements for NUMA-based systems, an "-o flush" mount option aimed at FAT-based hotpluggable media devices (mp3), physical CPU hotplug and memory hot-add in x86-64, support for compiling x86 kernels with the GCC stack protection, and many other things. You can check the full list of changes in LinuxChanges."

GFS2

Anyone know if any reviews of GFS2 in actual use compared to other clustered filesystems?

TPM encryption

[Pausanias]

Very interesting how ecryptfs [lwn.net] uses the TPM module for encryption. While there is plenty to worry about regarding treacherous computing [wikipedia.org], it is nice to see that the TPM can be put to uses that actually bolster privacy. This still does not prevent a possible future dystopia [gnu.org], but it still goes to show that devices such as TPM are not necessarily "pure evil."

TPM is neither good nor bad

How operating systems and applications use TPM can be good or evil

In all that I've read about TPM, I've concluded that TPM is not much more than a glorified hardware based public/private key management system. The reference implementations I seen attach to the same slow hardware buses that PS/2 keyboard and mice sit. There is not enough bandwidth on that bus to encrypt/decrypt whole disks in real time.
