.SH NAME
__d_drop \- drop a dentry
.SH SYNOPSIS
.sp
\fB
.sp
void __d_drop  (struct dentry * \fIdentry\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIdentry\fB\fR
dentry to drop
.SH "DESCRIPTION"
.PP
\fBd_drop\fR 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.
.PP
\fBd_drop\fR is used mainly for stuff that wants
to invalidate a dentry for some reason (NFS
timeouts or autofs deletes).
