 Reverting to the revisions prior to this commit fixes the problem (and also
 makes all resize_fs tests work as expected again):

 Log Message:
 - Improve PUFFS_KFLAG_CACHE_FS_TTL by reclaiming older inactive nodes.
 ..
 ..
 We fix this by introducing a lookup count in kernel and userland. On
 reclaim, the kernel sends the count, which enable userland to detect
 situation where it initiated a lookup that is not completed in kernel.
 In such a situation, the reclaim must be ignored, as the node is about
 to be looked up again.
