Subject: [130/165] ext4: Conditionally define compat ioctl numbers
Date: Fri, 30 Jul 2010 10:15:58 -0700 [thread overview]
Message-ID: <20100730171511.435378447@clark.site> (raw)
In-Reply-To: <20100730171550.GA1299@kroah.com
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
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.
