This commit message is incorrect because f2fs_encrypted_inode() isn't actually
removed by this patch. Did you mean to remove it? I think you can if you
change f2fs_encrypted_file() to:
static inline bool f2fs_encrypted_file(struct inode *inode)
{
return IS_ENCRYPTED(inode) && S_ISREG(inode->i_mode);
}
... and if you replace the other calls to f2fs_encrypted_inode() with
file_is_encrypt().
