Announcing the release of BFS for 3.4, along with the complete -ck1 patch.
Full 3.4-ck1 patches:
Alas I was unable to keep the 420 number for BFS due to a number of minor changes. I also incremented the number beyond the unofficial 421 patch put to lkml so there was no confusion. The only changes are that some trivial display accounting fixes were added, along with forcing SLUB in the config by default as other SLAB allocators crash with BFS (you should all be using SLUB anyway). The rest of the BFS changes are a resync with the new code going into linux 3.4, along with more merging of code from mainline into BFS where suitable. Note that I have adopted the mainline approach of dealing with unplugged I/O. Previously I had spent a lot of time making it work with BFS for those who remember that period of instability, so hopefully the mainline approach will work seamlessly now (since mainline ended up having the same bug but it was harder to reproduce).
3.4-ck1 is just a resync of the remainder of the patches from 3.3-ck1.
EDIT: If you build on SMP without enabling CPU hotplug you will need this patch on top for BFS to build:
