Hi,
Here is the current GFS2 patch queue. You'll notice that this time there are no DLM patches in this list. That is because the DLM team are setting up their own git tree and this future DLM patches will be sent directly by them rather than via the GFS2 tree.
Most of this set of patches is clean up and bug fixes, there is really not a lot new this time. I guess the most significant thing is the patch to use ->page_mkwrite which will greatly increase efficiency when files opened r/w are mostly only accessed for reading across a cluster.
There are a number of cleanups related to journalling which is really where the largest number of changes in terms of code lines is. The indirect blocks for the journal are now scanned once only at mount time and the bmap information is retained in the form of an extent list. Since we expect journals to consist of only a single extent in the normal case, this should generally be quite a short list :-)
In addition some of the tunables relating to the journal have been removed in favour of autotuning those variables.
Steve.
