Few days ago was officially released the new Linux 3.2 kernel. The new release includes support for ext4 block sizes bigger than 4KB and up to 1MB, which improve performance with big files; btrfs has been updated with faster scrubbing, automatic backup of critical filesystem metadata and tools for manual inspection of the filesystems; the process scheduler has added support to set upper limits of CPU time; the desktop reponsiveness

in presence of heavy writes has been improved, TCP has been updated to include an algorithm which speeds up the recovery of the connection after lost packets; the profiling tool “perf top” has added support for live inspection of tasks and libraries and see the annotated assembly code; the Device Mapper has added support for ‘thin provisioning’ of storage, and a new architeture has been added: the Hexagon DSP processor from Qualcomm. Other drivers and small improvements and fixes are also available in this release.
