Yes, but a lot comes from commercial Unix. Ext3 is simply ext2 with
journalling added, where ReiserFS, JFS and XFS are designed around
journalling. 

Journalling really has nothing to do with the bulletproofing of a file
system per se. The reason to use a journalling file system has more to
do with crash recovery time than with integrity. IMHO, most Unix/Linux
file systems run without any significant problems for years
