---- Log message:
- up to 3.1.7; po patch merged upstream; add patches: 1) avoid hanging on futexes, 2) lower memory footprint, 3) use libtcmalloc which uses less memory than glibc malloc (which means 5.3GB of ram needed instead of 7.3GB for 7.1TB fs with 95mln inodes).

+Instead of allocating inode records in chunks and keeping a freelist of them
+which gets released to the system memory allocator in one go use plain malloc
+and free for them.  The freelist just means adding a global lock instead
+of relying on malloc and free which could be implemented lockless.  In
+addition smart allocators like tcmalloc have far less overhead than our
+chunk and linked list.
