From b25801038da5823bba1b5440a57ca68afc51b6bd Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 9 Mar 2007 16:53:21 -0800 Subject: ocfs2: Support xfs style space reservation ioctls We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to allocate and deallocate regions to a file without zeroing data or changing i_size. Though renamed, the structure passed in from user is identical to struct xfs_flock64. The three fields that are actually used right now are l_whence, l_start and l_len. This should get ocfs2 immediate compatibility with userspace software using the pre-existing xfs ioctls.
