d_really_is_positive(9)

💅 NAME 💅

okay bestie, this is the manual page for d_really_is_positive(9) from the Kernel API Manual, and it's here to tell you if a dentry is really positive — no fallthroughs pretending to be main characters 💖

✨ SYNOPSIS ✨

bool d_really_is_positive (const struct dentry *dentry );

🎀 ARGUMENTS 🎀

• dentry — the dentry in question. literally the little guy we're checking 🫶

🦋 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. no cap, that's the whole vibe check 🔥

Note! Two very important things, bestie: 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. stay in your own lane 💅 2. It should also be used in combination with d_inode to get the inode. team effort, periodt ✨
