Pawel Jakub Dawidek 3f6043a57d When snapshot mount point is busy (for example we are still in it) ... we will fail to unmount it, but it won't be removed from the tree, so in that case there is no need to reinsert it. This fixes a panic reproducable in the following steps: # zfs create tank/foo # zfs snapshot tank/foo@snap # cd /tank/foo/.zfs/snapshot/snap # umount /tank/foo panic: avl_find() succeeded inside avl_add() Reported by: trasz MFC after: 3 days		2009-09-07 21:46:51 +00:00
