the 3.6 merge window on August
2, a couple of days earlier
than would have normally been expected. There were evidently two reasons
for that: a desire to send a message to those who turn in their pull
requests on the last day of the merge window, and his upcoming vacation.
In the end, he only pulled a little over 300 changes since the previous merge window summary
, with the
result that 8,587 changes were pulled in the 3.6 merge window as a whole.
Those 300+ changes included the following:
- The block I/O bandwidth controller has been reworked so that each
control group has its own request list, rather than working from a
single, global list. This increases the memory footprint of block I/O
control groups, but makes them function in a manner much closer to the
original intention when lots of requests are in flight.
- A set of restrictions on the creation of
hard and soft links has been added in an attempt to improve
security; they should eliminate a lot of temporary file
- The device mapper dm-raid module now supports RAID10 (a combination of
striping and mirroring).
- The list of new hardware support in 3.6 now includes OMAP DMA engines.
- The filesystem freeze functionality has been reimplemented to be more
robust; in-tree filesystems have been updated to use the new mechanism.
The process of stabilizing all of those changes now begins; if the usual
patterns hold, the final 3.6 kernel can be expected sometime in the second
half of September.
