generic_rea...le_tree_page(9) 🦋

okay so bestie, this little page comes straight from the Kernel API Manual, and it’s all about one very specific helper. no cap, it’s giving “I do one job and I do it slayfully” energy. 💅

🌸 NAME 🌸

generic_read_merkle_tree_page — generic ->read_merkle_tree_page helper ✨

✨ SYNOPSIS ✨

struct page * generic_read_merkle_tree_page (struct inode *inode ,
       pgoff_t index );

💅 ARGUMENTS 💅

• inode — the inode containing the Merkle tree 🎀
• index — 0-based index of the Merkle tree page in the inode ⭐

🔥 DESCRIPTION 🔥

The caller needs to adjust index from the Merkle-tree relative index passed to ->read_merkle_tree_page to the actual index where the Merkle tree is stored in the page cache for inode. literally that’s the whole vibe of this helper, and it ate. 💖
