(sys_msgrcv): New function.
(msgrcv): Use it instead of msgrcv. Add bits to mtype,
check for -mtype in msgrcv.
Apparently, BPF_F_RDONLY and BPF_F_WRONLY are also used in map_flags.
Moreover, set of flags depends on the type of map, but let's leave that
for another day.
* xlat/bpf_map_flags.in (BPF_F_RDONLY, BPF_F_WRONLY): New constants.
(BPF_F_STACK_BUILD_ID): New constant, introduced by Linux commit
v4.17-rc1~148^2~156^2~3^2~1.
* xlat/bpf_map_flags.in: Update expected output.
* tests/fcntl.c (TEST_F_OWNER_EX): New macro.
[TEST_F_OWNER_EX]: Include "f_owner_ex.h".
[TEST_F_OWNER_EX] (test_f_owner_ex_type_pid,
test_f_owner_ex_umove_or_printaddr, test_f_owner_ex): New functions.
(main) [TEST_F_OWNER_EX]: Use test_f_owner_ex.

Since Linux 4.16, kernel appends the cpuid as suffix to the entry
for a kvm vcpu in /proc/$pid/fd like:
anon_inode:kvm-vcpu:0
That was
anon_inode:kvm-vcpu
This kernel change causes the test case failure on newer kernels.
Update the test to deal with the new name as well as the old one.
* tests/ioctl_kvm_run.c: Include unistd.h for using readlink(2).
(vcpu_dev_should_have_cpuid): New function for detecting whether
a proc entry for given fd has the cpuid suffix or not.

(MPERS_PRINTER_DECL(btrfs_ioctl)) <case BTRFS_IOC_DEV_REPLACE>: Print
named values for the
struct btrfs_ioctl_dev_replace_args.start.cont_reading_from_srcdev_mode
field.
* tests/btrfs.c: Include "xlat/btrfs_cont_reading_from_srcdev_mode.h".
(btrfs_test_dev_replace_ioctl): Update expected output.

the BTRFS_IOC_BALANCE_V2 call based on its return code.
For these volumes, pend/vend should be the same for data and meta.

args.meta.vend to the same values as args.data.pend and args.data.vend,
respectively.

(btrfs_test_ino_path_ioctls): Use dir_name for printing directory name.

Recent kernel siginfo changes, namely, v4.14-rc1~60^2^2~1,
v4.16-rc1~159^2~37, and v4.16-rc1~159^2~39, introduced ABI regressions
that render the whole siginfo interface unreliable.
Looks like the kernel side is not eager to fix the breakage,
so here is a workaround.

variables.
