  ext4: reject encrypted inodes when block size > page size (2026-10-24 12:58:37 -0700)

----------------------------------------------------------------

- Add more checks to prevent encryption on "large block size" ext4
  filesystems (s_blocksize > PAGE_SIZE), which isn't supported yet.
  There was already a mount-time check, but it wasn't enough.

- Add missing memory barrier to fscrypt_find_mode_key()

- Add missing zeroization in an error path
