nfsd_reply_cache_scan(9)

okay bestie, welcome to the Kernel API Manual — the icon of the hour is nfsd_reply_cache_scan(9) 💅✨

🌸 NAME 🌸

nfsd_reply_cache_scan — the scan_objects method for the DRC shrinker 🧹💖

✨ SYNOPSIS ✨

unsigned long nfsd_reply_cache_scan (struct shrinker *shrink , struct
shrink_control *sc );

🎀 ARGUMENTS 🎀

• shrink — our registered shrinker context. literally our own little shrinker passport 🫶
• sc — garbage collection parameters. the vibe-check settings for GC 🗑️✨

🦋 DESCRIPTION 🦋

okay so the job is: free expired entries on each bucket's LRU list until we've released nr_to_scan freed objects. that's the whole mission 💅

nothing gets released if the cache has not exceeded its max_drc_entries limit — like, the cache has to actually be over the limit before this starts letting things go 🚫📦

Returns the number of entries released by this call. that's the receipt 🧾✨
