+# The test makes use of inode-lru-limit to hit a scenario, where we
+# find an inode whose ancestry is not there. Following is the
+# hypothesis (which is confirmed by seeing logs indicating that
+# codepath has been executed, but not through a good understanding of
+# NFS internals).
+
+#     At the end of an fop, the reference count of an inode would be
+#     zero. The inode (and its ancestry) persists in memory only
+#     because of non-zero lookup count. These looked up inodes are put
+#     in an lru queue of size 1 (here). So, there can be at most one
+#     such inode in memory.
+
+#     NFS Server makes use of anonymous fds. So, if it cannot find
+#     valid fd, it does a nameless lookup. This gives us an inode
+#     whose ancestry is NULL. When a write happens on this inode,
+#     quota-enforcer/marker finds a NULL ancestry and asks
+#     storage/posix to build it.
