I tried the above and this is the output:
lrwxrwxrwx. 1 root root 51 Oct 26 17:56 /lib/modules/3.10.0-514.21.2.el7.x86_64/weak-updates/jfs/jfs.ko -> /lib/modules/3.10.0-514.el7.x86_64/extra/jfs/jfs.ko
lrwxrwxrwx. 1 root root 51 Oct 26 17:56 /lib/modules/3.10.0-514.26.1.el7.x86_64/weak-updates/jfs/jfs.ko -> /lib/modules/3.10.0-514.el7.x86_64/extra/jfs/jfs.ko

-rw-r--r--. 1 root root 302480 Apr 16 2017 /lib/modules/3.10.0-514.el7.x86_64/extra/jfs/jfs.ko
I also ran yum update again but it did not pick up kmod-jfs although it was just updated. How long time does it typically take for an updated package to become available?
