Hi, can I get a code review for 6861594 NFSv4 client Deadlock: cycle in blocking chain at nfs4_move_mi
Webrev: http://cr.opensolaris.org/~pavelf/6861594/ Background: If there are two threads doing a failover for differnet mounts at the same time, both of them need to grab the s_lock for the new and the old nfs server. To prevent a deadlock they must grab the s_locks it in the same order. nfs4_move_mi() is not safe since it does not guarantee the same order and allows the deadlock to happen. Thanks, Pavel
