ENUM D_WALK_RET(9)

✨ NAME ✨

okay so bestie, this is enum d_walk_ret(9) from the Kernel API Manual — literally the enum that tells you what action to take during tree walk. it’s giving “pick a lane” energy for dentries, no cap 🎀

🦋 SYNOPSIS 🦋

the synopsis is right here, verbatim, because code deserves accuracy:

       enum d_walk_ret {
           D_WALK_CONTINUE ,
           D_WALK_QUIT ,
           D_WALK_NORETRY ,
           D_WALK_SKIP

       };

💅 Constants 💅

okay so these are the four constants, and each one is its own little vibe check:

• D_WALK_CONTINUE — continue walk. keep it moving, bestie ✨
• D_WALK_QUIT — quit walk. bye, walk 👋
• D_WALK_NORETRY — quit when retry is needed. not me bailing the second retry shows up 💀
• D_WALK_SKIP — skip this dentry and its children. not them, not their kids, we’re skipping the whole little family 🦋
