I'm working on making ext4 and f2fs always do file contents en/decryption using fscrypt_set_bio_crypt_ctx(), which already supports large folios and doesn't require the filesystem to manage bounce buffers. I don't think these minor tweaks to the other implementation (which don't actually make it support large folios) accomplish anything useful, and we should focus on removing it instead. - Eric
