[PATCH] Minix V3 support
This morning I needed to read a Minix V3 filesystem, but unfortunately my
2.6.19 did not support that, and neither did the downloaded 2.6.20rc4.
Fortunately, google told me that Daniel Aragones had already done the work,
patch found at http://www.terra.es/personal2/danarag/
Unfortunaly, looking at the patch was painful to my eyes, so I polished it
a bit before applying. The resulting kernel boots, and reads the
filesystem it needed to read.
