IMHO, it will be nice to have active maintainer for autofs4, particularly for keeping autofs4 in sync with VFS layer changes. This is necessary as I found autofs4 interacting with VFS (dcache and vfsmount) in a way no other file system does. The problem is with is_tree_busy() routine where we check and depend on dentry ref count to find busy dentries. Though it is done under dcache_lock but I don't think taking dcache_lock will guarantee consistent reference count for dentries. We have other people doing dget() or dput() without taking dcache_lock. Further, introduction of RCU based dcache lookup in 2.5.61 it is more susceptible to races. So, I hope you will look into this problem also. Thanks Maneesh -- Maneesh Soni IBM Linux Technology Center, IBM India Software Lab, Bangalore.
