Subject: Fix bug when both crossmnt and fsid are set.
X-Git-Tag: nfs-utils-1-1-2~19
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=2d77e3a27b7b211f303fcc3a813a044838dad970;p=nfs-utils.git

Fix bug when both crossmnt and fsid are set.

When exported a filesystems with option inherited (by the crossmnt
option) from a higherlevel filesystem, ignore filesystem specific
options like FSID and explicit UUID.
