From: Christoph Hellwig Date: Thu, 21 Apr 2011 13:21:03 +0000 (+0000) Subject: xfs: add an x86 compat handler for XFS_IOC_ZERO_RANGE X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8c1fdd0be5498f852e00c5fbd9cb0c3969e46cc6;p=openwrt%2Fstaging%2Fblogic.git xfs: add an x86 compat handler for XFS_IOC_ZERO_RANGE XFS_IOC_ZERO_RANGE uses struct xfs_flock64, and thus requires argument translation for 32-bit binaries on x86. Add the required XFS_IOC_ZERO_RANGE_32 defined and add it to the list of commands that require xfs_flock64 translation.
