Subject: hibernate and file system/metadisk driver buffers/caches

>From what I have found in Documentation/power, I should be
able to hibernate a system to a partition on flash, and
resume it, preserving its entire state.

In case I missed something, though, does anyone know if,
in particular, MD stripe buffers are preserved, as well
as the EXTn/XFS buffers/caches?  I think I read that I/O
buffers in use by drivers are saved only if the driver
has the appropriate suspend() interfaces.
