Now if we remove the device that is specified when mounting, btrfs will update
the mount information in /proc, such as the information in /proc/mounts. So
in order to guarantee the consistency between /etc/mtab and the mount
information in /proc, we must update /etc/mtab. This patch does it.

This patch need libmount and libmount-devel(version >= 2.19) packages to
compile.

Does this work well with say Fedora where /etc/mtab is just a symlink to
/proc/mounts?  Thanks,

Yes, if /etc/mtab is not a regular file, we will skip the update. And I have
do some test for it and all of them passed.

This patch can not work well on your machine?

It didn't but I think I screwed something up so ignore me.  Thanks,

Josef
