Following are a bunch of patches that I'm planing to submit in the
next merge window (which I expect to open just after LWN publishes
this week :-).
There is nothing really exciting - mostly clean-up patches that are
the product of the development some other features that I'm still
working on (like reshaping some RAID10 arrays to more devices).
The features here are:
- RAID10 can grow or shrink to match changes in the underlying
devices.
- linear, RAID0, RAID1, RAID10 now call the merge_bvec_fn in
member devices, so that if you stack one of these atop
LVM or RAID0 or similar, it won't insist on breaking all
requests up into single page requests for the path through the
multiple layers.
Review, as always, is most welcome.
