.SH "NAME"
d_really_is_positive \- Determine if a dentry is really positive (ignoring fallthroughs)
.SH "SYNOPSIS"
.HP \w'bool\ d_really_is_positive('u
.BI "bool d_really_is_positive(const\ struct\ dentry\ *\ " "dentry" ");"
.SH "ARGUMENTS"
.PP
\fIconst struct dentry * dentry\fR
.RS 4
The dentry in question
.RE
.SH "DESCRIPTION"
.PP
Returns true if the dentry represents a name that maps to an inode (ie\&. \->d_inode is not NULL)\&. The dentry might still represent a whiteout if that is represented on medium as a 0,0 chardev\&.
.PP
Note! (1) This should be used *only* by a filesystem to examine its own dentries\&. It should not be used to look at some other filesystem\*(Aqs dentries\&. (2) It should also be used in combination with
\fBd_inode\fR
to get the inode\&.
