folio_batch...exceptionals(9)

🎀 folio_batch_remove_exceptionals 🎀

Welcome to the Kernel API Manual, bestie — today’s main character is folio_batch_remove_exceptionals, and she is literally all about pruning non-folios from a batch. ✨

💖 NAME 💖

folio_batch_remove_exceptionals — prune non-folios from a batch. That’s the whole assignment, and she ate. 💅

✨ SYNOPSIS ✨

void folio_batch_remove_exceptionals (struct folio_batch *fbatch );

🎀 ARGUMENTS 🎀

• fbatch — the batch to prune. That’s it, that’s the whole argument, bestie. 🫶

🦋 DESCRIPTION 🦋

Okay so find_get_entries fills a batch with both folios and shadow/swap/DAX entries. This function prunes all the non-folio entries from fbatch without leaving holes, so that it can be passed on to folio-only batch operations. Cleanup queen behavior, no cap. 🔥
