+Subject: [PATCH] libinstaller: Avoid using <linux/ext2_fs.h>
+
+Don't use <linux/ext2_fs.h> if we can avoid it.
+
+The ioctl constants have been globalized and moved to <linux/fs.h>.
+Use a private copy of ext2_fs.h from e2fsprogs with the ioctl
+constants removed for the data structures.
+
+Do at least attempt backward compatibility for old kernel headers, but
+no real hope of proper operation there...
+
+Signed-off-by: H. Peter Anvin <hpa@zytor.com>
