Some ioctls have flags fields that are 64-bit. A 32-bit val means
these flags will never be matched or printed.
* util.c:
(xlookup) Use uint64_t for val.
(xlat_search) Likewise.
(printxvals) Likewise.
(addflags64) New function.
(printflags64) New function.
(sprintflags64) New function
Hi all -
This short series adds support for the btrfs ioctls. Its structures
make heavy use of __u64 so rather than cast every single member, I added
new PRI* macros to print them properly. It also uses 64-bit flags and
defines values that are larger than can be described by a 32-bit
variable, s
Rather than cast every __u64 or __s64 before printing, we can
define printing helpers for those types directly.
* defs.h: define PRI__[uxs]64.

This commit is already merged.
I changed PRI__s64 to PRI__d64 in a follow-up commit

First, you've forgotten to include file_ioctl.c into the patch.
