1. NAME▲

__d_drop - drop a dentry

2. SYNOPSIS ▲

void __d_drop(struct dentry *  dentry );

3. ARGUMENTS ▲

dentry
    dentry to drop

4. DESCRIPTION ▲

d_drop unhashes the entry from the parent dentry hashes, so that it wonAqt be found through a VFS lookup any more. Note that this is different from deleting the dentry - d_delete will try to mark the dentry negative if possible, giving a successful _negative_ lookup, while d_drop will just make the cache lookup fail.

d_drop is used mainly for stuff that wants to invalidate a dentry for some reason (NFS timeouts or autofs deletes).

__d_drop requires dentry->d_lock.
