Kernel release status
So on the whole, this remains a rather calm release cycle until the very end. And with the release of 4.3, obviously the merge window for 4.4 is open, and let's keep our fingers crossed that that will be an equally calm release." 4.3 includes the ability to add BPF programs to user-space probes, the "PIDs controller" (an anti-fork-bomb measure), the removal of the ext3 filesystem, support for identifier locator addressing, the ability to handle page faults in user space, and more.
The 4.4 merge window is now open, but has gotten off to a relatively slow start; full merge-window coverage will be found in next week's Kernel Page.
Stable updates: none have been released in the last week.
