.SH NAME
__d_find_alias \- grab a hashed alias of inode
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
struct dentry * __d_find_alias  (struct inode * \fIinode\fB, int \fIwant_discon\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIinode\fB\fR
inode in question
.TP
\fB\fIwant_discon\fB\fR
flag, used by d_splice_alias, to request
that only a DISCONNECTED alias be returned.
.SH "DESCRIPTION"
.PP
If inode has a hashed alias, or is a directory and has any alias,
acquire the reference to alias and return it. Otherwise return NULL.
Notice that if inode is a directory there can be only one alias and
it can be unhashed only if it has no children, or if it is the root
of a filesystem.
.PP
If the inode has a DCACHE_DISCONNECTED alias, then prefer
any other hashed alias over that one unless \fIwant_discon\fR is set,
in which case only return a DCACHE_DISCONNECTED alias.
