This patch set contains a trivial printf format fix, followed by two
new features for the blklogwrites driver.
The first feature is an option to append to an existing log, adopting
its sector size and other metadata in its superblock. This can be
useful, and was suggested by Kevin Wolf.
The second feature is an option for specifying how often the log
superblock is updated, in terms of number of total write entries
logged. This ensures that the log superblock is relatively up-to-date
even in the face of abnormal QEMU shutdown.
