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.

9311aa6483 fix compile failed with libc musl (#103) 
There is a failure while compiling with libc musl:
[snip]
|./block-cache/io_engine.h:18:17: error: expected
unqualified-id before numeric constant
|  unsigned const PAGE_SIZE = 4096;
[snip]

The musl defeines macro PAGE_SIZE, undef it conditionally
could fix the issue.

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:
/usr/include/boost/optional/optional.hpp: In instantiation of ‘std::basic_ostream<_CharT, _Traits>& boost::operator<<(std::basic_ostream<_CharT, _Traits>&, const boost::optional_detail::optional_tag&) [with CharType = char; CharTrait = std::char_traits<char>]’:
./base/indented_stream.h:31:9:   required from ‘{anonymous}::indented_stream& {anonymous}::indented_stream::operator<<(const T&) [with T = boost::optional<unsigned int>]’
contrib/thin_sexp_emitter.cc:105:29:   required from ‘void {anonymous}::sexp_emitter::kv(const char*, const T&) [with T = boost::optional<unsigned int>]’
contrib/thin_sexp_emitter.cc:29:21:   required from here
/usr/include/boost/optional/optional.hpp:1481:3: error: static assertion failed: If you want to output boost::optional, include header <boost/optional/optional_io.hpp>
   BOOST_STATIC_ASSERT_MSG(sizeof(CharType) == 0, "If you want to output boost::optional, include header <boost/optional/optional_io.hpp>");
   ^~~~~~~~~~~~~~~~~~~~~~~
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.

a recursive lock. (issue #97)

6a7351da0d Fix musl build (#96) 
a) Fix build if limits.h provides definition for PAGE_SIZE, as musl does w/musl per XSI[1] although it's apparently optional [2].
   This value is only provided when it's known to be a constant, to avoid the need to discover the value dynamically.
b) If not using system-provided (kernel headers, or libc headers, or something) use the POSIX approach of querying the value
   dynamically using sysconf(_SC_PAGE_SIZE) instead of hardcoded value that hopefully is correct.
