The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Bug fix in BTF deduplication that was mishandling an equivalence
   comparison, from Andrii.

2) libbpf Makefile fixes to properly link against libelf for the shared
   object and to actually export AF_XDP's xsk.h header, from Bj√∂rn.

3) Fix use after free in bpf inode eviction, from Daniel.

4) Fix a bug in skb creation out of cpumap redirect, from Jesper.

5) Remove an unnecessary and triggerable WARN_ONCE() in max number

+Description:   Device DAX is the device-centric analogue of Filesystem
+               DAX (CONFIG_FS_DAX).  It allows memory ranges to be
+               allocated and mapped without need of an intervening file
+               system.  Device DAX is strict, precise and predictable.
+               Specifically this interface:
+
+               1/ Guarantees fault granularity with respect to a given
+               page size (pte, pmd, or pud) set at configuration time.
+
+               2/ Enforces deterministic behavior by being strict about
+               what fault scenarios are supported.
+
+               The /sys/class/dax/ interface enumerates all the
+               device-dax instances in the system. The ABI is
+               deprecated and will be removed after 2020. It is
+               replaced with the DAX bus interface /sys/bus/dax/ where
+               device-dax instances can be found under
+               /sys/bus/dax/devices/
