From 3e63cbb1efca7dd3137de1bb475e2e068e38ef23 Mon Sep 17 00:00:00 2001 From: Ankit Jain Date: Fri, 19 Jun 2009 14:28:07 -0400 Subject: fs: Add new pre-allocation ioctls to vfs for compatibility with legacy xfs ioctls This patch adds ioctls to vfs for compatibility with legacy XFS pre-allocation ioctls (XFS_IOC_*RESVP*). The implementation effectively invokes sys_fallocate for the new ioctls. Also handles the compat_ioctl case. Note: These legacy ioctls are also implemented by OCFS2.
