NAME

6       d_really_is_negative - Determine if a dentry is really negative
7       (ignoring fallthroughs)
8

SYNOPSIS

10       bool d_really_is_negative(const struct dentry * dentry);
11

ARGUMENTS

13       dentry
14           The dentry in question
15

DESCRIPTION

17       Returns true if the dentry represents either an absent name or a name
18       that doesn't map to an inode (ie. ->d_inode is NULL). The dentry could
19       represent a true miss, a whiteout that isn't represented by a 0,0
20       chardev or a fallthrough marker in an opaque directory.

22       Note! (1) This should be used *only* by a filesystem to examine its own
23       dentries. It should not be used to look at some other filesystem's
24       dentries. (2) It should also be used in combination with d_inode to get
25       the inode. (3) The dentry may have something attached to ->d_lower and
26       the type field of the flags may be set to something other than miss or
27       whiteout.
