de7c9a5781 [thin_journal_check] Checks journal of block manager activity. 
You need to apply doc/bm-journal.patch to create the journal.

thin_journal_check confirms that if the machine had crashed at any time
during the test run no metadata corruption would have occured.

1311447a94 [build] Include boost/optional/optional_io.hpp in thin-provisioning/emitter.h (#102) 
This fixes following build failure with Boost 1.67.0:
```
In file included from /usr/include/boost/optional/optional.hpp:33,
                 from /usr/include/boost/optional.hpp:15,
                 from ./thin-provisioning/emitter.h:23,
                 from contrib/thin_sexp_emitter.cc:2:

   ^~~~~~~~~~~~~~~~~~~~~~~
make: *** [contrib/Makefile:15: contrib/thin_sexp_emitter.o] Error 1
```

boost/optional/optional_io.hpp exists since at least Boost 1.34.0, so it is
 safe to include in older versions, too.

b7d418131d Spin-off syscall-related file operations (#78) 
* [file_utils] spin-off syscall-related file operations

1. Eliminate the potential circular dependency between
   persistent-data/block.h and persistent-data/file_utils.h,
   if the former one wants to include the latter.
2. Avoid namespace pollution by removing the "using namespace std"
   declaration in block.tcc.
3. Correct the header hierarchy: base/xml_utils.h now no longer
   depends on the higher-level persistent-data/file_utils.h

* [file_utils] support block files in get_file_length()

2815aeace9 [thin_repair] fix regression in thin_repair 
When opening the corrupted metadata we don't need to touch the space
maps.  This used to be achieved by pretending we were opening a
metadata snap at block 0 (superblock location).  But got changed in
the recent rationalisation of the metadata constructors.

This patch introduces a bool to the metadata OPEN constructor that
says whether the space maps are needed or not.
