I can confirm that 3.15.2 definitely has the deadlock problem. I tried upgrading just to convince myself of this before patching it and it only took a few hours before it stopped syncing with the usual errors. I applied the patch on Jun 28 around 20:00UTC. I haven't had a deadlock since, despite having the file system fairly active with a few reboots, some deleted snapshots, being assimilated by the new sysvinit replacement, etc. That doesn't really prove anything though - for all I know it will hang a week from now. However, the patch seems stable so far on 3.15.2.
