[Cluster-devel] [PATCH] Handle multiple filesystems on a single mountpoint



Hello,


Here is a patch against gfs1-utils.git

Use-case:
When both a GFS and a GFS2 filesystems are mounted on the same mountpoint,
# umount /example
/sbin/umount.gfs2: /example is not a gfs2 filesystem
/sbin/umount.gfs: /example is not a gfs filesystem
/sbin/umount.gfs2: /example is not a gfs2 filesystem


Best regards,
