* [PATCH 0/6] btrfs-progs: add support for LOGICAL_INO_V2 features in logical-resolve

This patch set adds support for LOGICAL_INO_V2 features:

        - bigger buffer size (16M instead of 64K, default also increased to 64K)

        - IGNORE_OFFSETS flag to look up references by extent instead of block

If the V2 options are used, it calls the V2 ioctl; otherwise, it calls
the V1 ioctl for old kernel compatibility.

Same as LOGICAL_INO, except a different magic number.

Increase the maximum buffer size to SZ_16M.

Add an option (-o) to set the ..._IGNORE_OFFSET flag.

If the buffer size is greater than 64K or the IGNORE_OFFSET option
is used, call ioctl V2; otherwise, use ioctl V1 to be compatible with
older kernels.

Filesystems with nontrivial snapshots or dedupe will easily overflow
a 4K buffer.  Bump the size up to the largest size supported by the
V1 ioctl.

Nit^2:  That was the kernel patch, this is a btrfs-progs patch to use
the kernel feature.

I'm assuming kernel and userspace patches get different version
numbering...?
