__D_DROP(9) | The Linux VFS | __D_DROP(9) |
NAME¶
__d_drop - drop a dentry
SYNOPSIS¶
void __d_drop(struct dentry * dentry);
ARGUMENTS¶
dentry
dentry to drop
DESCRIPTION¶
d_drop unhashes the entry from the parent dentry hashes, so that it won´t 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.
