Subject: [PATCH v2.6.32.y 51/53] ext4: Conditionally define compat ioctl numbers

From: Ben Hutchings <ben@...adent.org.uk>

commit 899ad0cea6ad7ff4ba24b16318edbc3cbbe03fad upstream (as of v2.6.34-git13)

It is unnecessary, and in general impossible, to define the compat
ioctl numbers except when building the filesystem with CONFIG_COMPAT
defined.
