+Subject: [PATCH] export: fix handling of error from match_fsid()
+
+If match_fsid() returns -1 we shouldn't assume that the path definitely
+doesn't match the fsid, though it might not.
+This is a similar situation to where an export is expected to be a mount
+point, but is found not to be one.  So it can be handled the same way,
+by setting 'dev_missing'.
+This will only have an effect is no other path matched the fsid, which
+is what we want.
+
+The current code results in nothing being exported and any export point,
+or any mount point beneath a crossmnt export point fail a 'stat'
+request, which is too harsh.
