Subject: No point in rewind() mtab in zfs_unshare_proto(). We're not really
X-Git-Url: https://git.camperquake.de/gitweb.cgi?p=zfs.git;a=commitdiff_plain;h=abbfdca483897d4406889e3517e77baf07573ecb

No point in rewind() mtab in zfs_unshare_proto(). We're not really
reading the file, but instead use libzfs_mnttab_find() which does
the nessesary freopen() for us.
