 Hi,
 
 The error case of vfs_suspend means we keep on holding vfs_suspend_lock.
 vrevoke_suspend_next will convey the failure by returning NULL, but I
 think vrevoke might not be checking for that.
 
 unionfs seems to be the only one not using genfs_suspendctl, so possibly
 the odd one and the reason no one else is seeing this.
 ./unionfs/unionfs_vfsops.c:	.vfs_suspendctl = (void *)eopnotsupp,
