Subject[34-longterm 024/260] ext4: Conditionally define compat ioctl numbers
Date
From: Ben Hutchings <ben@decadent.org.uk>

commit 899ad0cea6ad7ff4ba24b16318edbc3cbbe03fad upstream.

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