This does not affect normal filesystems as long as they follow proper dcache interfaces. Care should be taken (like holding per dentry lock) if one is racing with d_lookup bringing a new dentry in dcache. - Since 2.5.75-bk1 onwards separate lock is used for vfsmounts instead of dcache_lock. -- Maneesh Soni IBM Linux Technology Center, IBM India Software Lab, Bangalore.
