I didn't notice this before, but the fscrypt_ctx isn't actually used at all in
the "own pages" crypto case. So there's really no need to allocate one. How
about we just handle the "own pages" case at the beginning of
fscrypt_encrypt_page():
if (inode->i_sb->s_cop->flags & FS_CFLG_OWN_PAGES) {
err = do_page_crypto(inode, FS_ENCRYPT, lblk_num, page, page,
len, offs, gfp_flags);
if (err)
return ERR_PTR(err);
return page;
}
(and the rest essentially the same as it used to be)
