+Subject: [PATCH] Fix building with Linux kernel 2.6.28 and later.
+
+With changeset 30c40d2c01f68c7eb1a41ab3552bdaf5dbf300d4 of the Linux
+kernel, the functions open_bdev_excl and close_bdev_excl were replaced with
+functionally-equivalent open_bdev_exclusive and close_bdev_exclusive.
+
+The new interface uses fmode_t instead of integer flags to carry on the
+opening mode for a block device, thus require some minor changes in the
+calls.
