"__D_DROP" "9" "July 2007" "Kernel Hackers Manual 2.6.22" "The Linux VFS"

NAME

__d_drop - drop a dentry

SYNOPSIS

"void __d_drop(struct dentry * " "dentry" ");"


ARGUMENTS

dentry

dentry to drop

DESCRIPTION

d_dropfR
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_dropfR
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.
