Without your patches, "dbench -x" was pretty much instantly causing the
threads to lock up, forcing me to reboot the box. With LOCKDEP enabled,
warnings were printed. After applying your patches (and a reboot) I've run
"dbench -x" for quite a while now with different runtimes and number of
clients and it's not locking up any more. I've tested with:

CONFIG_REISERFS_FS=y
CONFIG_REISERFS_CHECK=y
CONFIG_REISERFS_PROC_INFO=y
CONFIG_REISERFS_FS_XATTR=y
CONFIG_REISERFS_FS_POSIX_ACL=y
# CONFIG_REISERFS_FS_SECURITY is not set

...and a few "Kernel hacking" options set. Full config and dmesg:

(although I'm not really testing -rc1 but latest mainline -git
and your changes pulled)

So, feel free to add:

Tested-by: Christian Kujau <lists@nerdbynature.de>

I can't help with the code review though :-\

Thanks!
Christian.
