When the fast restart mode of Windows 8 (or later) is activated, the
log file format is different (version 2.0 instead of 1.1), having 32
temporaty blocks instead of 2. This patch upgrades ntfsrecover to take
the new format into account.
This is done to match the type of the LSN struct members in layout.h.
The effect of this change is that while these members were declared with
the le64 type previously, leLSN resolves to sle64. I.e. what was
previously unsigned fields are now signed.
Following this change we also need to switch over a few macros from
unsigned to signed versions in the code that uses these struct
definitions.
ntfsrecover applies to the metadata the updates which were requested on
Windows but could not be completed because they were interrupted by
some event such as a power failure, a hardware crash, a software crash
or the device being unplugged. Doing so, the file system is restored
to the latest consistent state.
No update to libntfs-3g is required by this implementation.
