DCACHE_DISCONNECTED) dentry is allocated and attached.
In the case of a directory, care is taken that only one dentry
can ever be attached.
- d_splice_alias(inode, dentry) or d_materialise_unique(dentry, inode)
- will introduce a new dentry into the tree; either the passed-in
- dentry or a preexisting alias for the given inode (such as an
- anonymous one created by d_obtain_alias), if appropriate. The two
- functions differ in their handling of directories with preexisting
- aliases:
- d_splice_alias will use any existing IS_ROOT dentry, but it will
- return -EIO rather than try to move a dentry with a different
- parent. This is appropriate for local filesystems, which
- should never see such an alias unless the filesystem is
- corrupted somehow (for example, if two on-disk directory
- entries refer to the same directory.)
- d_materialise_unique will attempt to move any dentry. This is
- appropriate for distributed filesystems, where finding a
- directory other than where we last cached it may be a normal
- consequence of concurrent operations on other hosts.
- Both functions return NULL when the passed-in dentry is used,
- following the calling convention of ->lookup.
