To install the kernel-plus:

# yum --enablerepo=centosplus install kernel-plus

Boot into the just installed kernel-plus and check to see if jfs is
working as expected. If all is fine, change the default kernel to

# yum-config-manager --setopt=centosplus.includepkgs=kernel-plus
--enablerepo=centosplus --save
# sed -e 's/^DEFAULTKERNEL=kernel$/DEFAULTKERNEL=kernel-plus/' -i

I would not say there is any downside, but I'm highly biased. ;)
