Let's be clear about this, the ReiserFS code merged into 2.4.1 did have
problems, which were slowly sorted through 2.4.4. What you have to
understand is that SuSE users have been prefering and using Reiser
successfully without problems for since 6.3 release, without these major
problems. The serious problems were almost always with the merge, and
inadequete testing by kernel maintainers. If you look round some of the
Kernel reports on news sites, you'll see why. It's not secret that 2.4
hasn't exactly been stable, and that Linus is regarded as better development
tree manager than stable release, hence most distro's used -ac series. The
fact is that anyone using straight Linux release kernels through 2.4 has had
a rocky ride, just look at 2.4.11 for one example, and 2 others didn't even
compile.

From what I read just today discussing it, it's catching up BSD with ext2
rather than putting it into the new Reiser/XFS/JFS/ext3 territory. If
softupdates were actually quicker than what Linux has now, you can be very
sure someone would be porting it.
Alot of code is shared between Linux and BSD, many SCSI drivers are ports for
example. Rick van Riel is currently developing an rmap VM based on Free BSD
VM ideas by their VM guru.
In many ways I think it's a shame that LUGs are Linux User Groups, rather
than Unix User groups or Free UNIX user groups, or something of the like.
