For Wednesday, November 25th, 2009, I’m Jon Masters with a summary of today’s LKML traffic.

In today’s issue: GFS2, Kconfig, PATA, and perf.

GFS2. Steven Whitehouse posted an “extra early pre-pull patch” due to the “larger than usual” number of changes in the latest version. The changes to GFS2 include the usual bug fixes, but also a cleaned up ACL implementation (including support for ACL caching), XFS-style quota support (with netlink quota notification over a modified dquot netlink interface), and much more.

Kconfig. Michal Marek posted a patch implementing support for custom one-line comments surrounding configuration entires in the .config file. This allows users to add comments such as “# some remark” around “CONFIG_FOO=y”. Separately, Nir Tzachar posted version 7 of his “nconfig” patches that implement an ncurses based replacement for menuconfig.

PATA. Bartlomiej Zolnierkiewicz posted an 86(!) part patch series implementing a large number of cleanups to the PATA drivers, intending to bring any last straglers onto par with their older IDE counterparts (the intention is to eventually kill off the legacy “IDE” layer).

Perf. Tom Zanussi posted version 2 of a 7 part patch series implmenting general purpose scripting support for perf trace. The patches create a generic interface through which one can expose the binary output ofr “perf trace” without having to parse the human readable ASCII version – i.e. a non-binary more easily parsed ASCII output alternative for perf. A perl example is included, for those who aren’t scared by the word “perl”.

The latest kernel release is 2.6.32-rc8.

Stephen Rothwell posted a linux-next tree for November 25th. Since Tuesday, there was a new tree (spi), the microblaze, ubifs, mfd, and alacrity trees lost their conflicts, while the ext3, rr, voltage, trivial, and percpu gained issues. The total sub-tree count increased to 154 with the new tree.
