[sheepdog] [PATCH 0/3] use struct vnode_info in recovery

[Christoph Hellwig]

This series switches struct vnode_info in recovery and cleans the code
up.  It does not yet reuse the existing and previous vnode info
structures from the cluster code, but prepares nicely for that.  I'd
like to get this first round of cleanups in ASAP given that recovery
seems to be a fairly active area currently.

The actual changes to reuse the vnode_info and ths not reading the epoch
log everytime in recovery will come after a few more infrastructure
changes.
