reiser4 and 2.5.60

[Ookhoi <ookhoi@humilis.net>]

Hi Oleg,

I builded a kernel with these options, like you told in your other mail
(which I lost, hence this new mail).

CONFIG_REISER4_FS=y
CONFIG_REISER4_CHECK=y
CONFIG_REISER4_DEBUG=y
CONFIG_REISER4_DEBUG_MODIFY=y
CONFIG_REISER4_DEBUG_MEMCPY=y
CONFIG_REISER4_DEBUG_NODE=y
CONFIG_REISER4_ZERO_NEW_NODE=y
CONFIG_REISER4_TRACE=y
CONFIG_REISER4_DEBUG_OUTPUT=y
CONFIG_REISERFS_FS=y

And disabled CONFIG_PREEMPT.

I still get a Segmentation fault when I want to untar a kernel source on
a fresh 512MB loop filesystem.

Does this help you?
