So in NTFS, the Master File Table is itself a file. That means it can have
extents. An easy way to process its records is thus to read it as a file
using functions in core/fs/fs.c.
However, the functions in core/fs/fs.c mostly assume the "global,"
Syslinux,
booted-from filesystem ('this_fs'). The Syslinux filesystem drivers try
to
tie all data to a particular FS instance.
So if an FS driver wants to open a file, it probably wants to do it _from_ a
particular FS instance, such as opening the MFT.
Anyway, please see commit bcb5af34d4fd02c5bd2970c89d30275cd9176168[1] and
please advise how this could be done better. For example, what are the
interfaces going to be like in the future, when code can specify a desired
filesystem to open a file on?
