okay so this little icon is straight out of the Kernel API Manual, and it's literally here to get the next valid key from a btree path array. bestie behavior, honestly 🫶

no cap, here's the whole signature:

okay bestie, here's what you're feeding it:

• btree — bmap struct of btree
• path — array of nilfs_btree_path struct
• minlevel — start level
• nextkey — place to store the next valid key

it returns 0 if the next key was found, and -ENOENT if not found. that's the whole vibe check 💅
