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;-) Signed-off-by: Tristan Ye <tristan.ye at oracle.com> --- fs/ioctl.c

The kernel patch series just sent (Subject: "Btrfs: scrub: print path to corrupted files and trigger nodatasum fixup") introduces two new ioctls to do in-kernel filesystem path construction. This series provides the corresponding userspace changes, adding two new commands to the btrfs utility: -- btrfs resolve inode [-v] <inode> <path> resolves an <inode> to all
