Description

We cow and set up the snapped inode locks based on whether WR/EXCL caps are issued. If that races with an in-flight cap update that releases those caps, the snapped inode state needs to get cleaned up.

This basically means recombining some of the FLUSHSNAP and regular cap update logic in Locker.cc.
