[2.6.0-test1] vfsmount_lock-fix

[Maneesh Soni]

Hi,

Please apply this patch for replacing dcache_lock with vfsmount_lock in 
put_namespace(). This was one obvious thing for which I felt very bad to miss.
Tested with CLONE_NEWNS flag also.

Thanks
Maneesh


- fix put_namespace() in namespace.h (replace dcache_lock with vfsmount_lock)
