STRUCT NILFS_PALLOC_CACHE(9)

💖 NAME 💖

okay so bestie, this is the manual page for struct nilfs_palloc_cache(9) from the Kernel API Manual — and we’re folding that title/manual-name situation right in here instead of doing the boring copy-paste header line, because we’re cute like that. The thing itself is the persistent object allocator cache. that’s the name, that’s the vibe, iykyk 💅

✨ SYNOPSIS ✨

       struct nilfs_palloc_cache {
           spinlock_t lock;
           struct nilfs_bh_assoc prev_desc;
           struct nilfs_bh_assoc prev_bitmap;
           struct nilfs_bh_assoc prev_entry;
        };

🌸 Members 🌸

these are the struct’s little icons, one by one, no cap 🫶

• lock — the cache protecting lock. it’s literally the lock doing the protecting for the cache.
• prev_desc — the blockgroup descriptors cache. lowkey holding those blockgroup descriptors.
• prev_bitmap — the blockgroup bitmap cache. yes bestie, bitmap cache, iconic.
• prev_entry — the translation entries cache. translation entries, cached, periodt.

🔥 SEE ALSO 🔥

• Kernel file ./fs/nilfs2/alloc.h — the way that this page points you to the next reads, fr fr:
  • nilfs_palloc_entries_per_group(9)
  • struct nilfs_palloc_req(9)
  • struct nilfs_bh_assoc(9)

and that’s a wrap, bestie 🎀 this page’s source/version is ./fs/nilfs2, it’s dated October 2026, and the title is struct nilfs_palloc_cache(9) — periodt. 💅🫶
