Linux Linux kernel 3.5 has been released. New features include support for metadata checksums in Ext4, userspace probes for performance profiling with systemtap/perf, a simple sandboxing mechanism that can filter syscalls, a new network queue management algorithm designed to fight bufferbloat, support for checkpointing and restoring TCP connections, support for TCP Early Retransmit (RFC 5827), support for android-style opportunistic suspend, btrfs I/O failure statistics, and SCSI over Firewire and USB. Here's the full list of changes.

Well, we know that there was a lot of pressure to merge google's drivers, which are incompatible without these new wake locks, and I suspect that's the prime reason these are being pushed into mainline.

I dislike that it's a system wide lock, it's a step back from the fine grained sleep states already supported by linux. It also adds a tight coupling between userspace and kernel. Now ordinary user space apps like gmail and google maps on android are responsible for system-wide power management, which seems silly to me.

Whatever the PM problems were with google's reference hardware, they should have fixed the hardware instead of adding these crazy wake locks.
