Can I have a feedback to insert this fs in the linux-next? From this
latest review I received some comments about how to fix some fs problems
on-the-fly without to clean all and restart. My next step will be to
write a simple fsck.pram to allow to fix these situations. However I
think the kernel code it's mature to be inserted in a pre-mainline
container. If I'll receive a positive feedback to my question, I'll
repost the patches to the last version (I updated the fs to be RCU aware
according to the work of Nick).
