d_instantiate_unique9
Instantiate a non-aliased dentry
Usage
struct dentry * d_instantiate_unique(struct dentry * entry, struct inode * inode);
Arguments
entry
dentry to instantiate
inode
inode to attach to this dentry
Overview
Fill in inode information in the entry. On success, it returns NULL. If an unhashed alias of “entry” already exists, then we return the aliased dentry instead and drop one reference to inode.
Note that in order to avoid conflicts with rename etc, the caller had better be holding the parent directory semaphore.
This also assumes that the inode count has been incremented (or otherwise set) by the caller to indicate that it is now in use by the dcache.
