Subject: ext4: Conditionally define compat ioctl numbers
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=899ad0cea6ad7ff4ba24b16318edbc3cbbe03fad;p=linux-beck.git

ext4: Conditionally define compat ioctl numbers

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