Reiserfs 3.5 disk format and kernel 2.6.0test9

Reiserfs 3.5 disk format and kernel 2.6.0test9

[Jorge Pérez Burgos (Koke)]

Hi,

	I have several partitions with 3.5.x reiserfs disk format, when i boot
up with kernel 2.6.0test9, i have these errors in each partition, even
though the system seems to work well:

buffer layer error at fs/buffer.c:431

This all looks like this newly discovered problem with 2.6.0-test9 + debian
patchset. Either unapply the part about not doing truncate_inode_pages() in
fs/block_dev.c::kill_bdev()

or apply this patch below which should also help.

Bye,
    Oleg
