d_really_is_positive: Determine if a dentry is really positive (ignoring fallthroughs)

NAME

d_really_is_positive - Determine if a dentry is really positive (ignoring fallthroughs)

SYNOPSIS

bool d_really_is_positive(const struct dentry dentry);

ARGUMENTS

dentry

The dentry in question

DESCRIPTION

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.

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's dentries. (2) It should also be used in combination with d_inode to get the inode.
