vfs_rename | vfs_rename - rename a filesystem object*@old_dir: parent of source*@old_dentry: source*@new_dir: parent of destination*@new_dentry: destination*@delegated_inode: returns an inode needing a delegation break*@flags: rename flags |
do_one_tree | |
d_invalidate | invalidate a dentry |
simple_fill_super | he inodes created here are not hashed. If you use iunique to generate* unique inode values later for this filesystem, then you must take care* to pass it an appropriate max_reserved value to avoid collisions. |
shrink_dcache_inode | Try to evict the inode's dentries from the dentry cache. If the inode is a* directory, then it can have at most one dentry; however, that dentry may be* pinned by child dentries, so first try to evict the children too. |
