[PATCH 1/3] VFS/ioctl: Add punching-hole support to ioctl().
We're currently support two paths from VFS to preallocate unwritten
extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of
punching-hole should be treated as the same, this patch tries to teach
file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2
is wise enough to do the rest of work;-)
