tools headers UAPI: Sync fcntl.h with the kernel sources to pick F_DUPFD_QUERY
There is no scrape script yet for those, but the warning pointed out we
need to update the array with the F_LINUX_SPECIFIC_BASE entries, do it.
Now 'perf trace' can decode that cmd and also use it in filter, as in:
root@number:~# perf trace -e syscalls:*enter_fcntl --filter 'cmd != SETFL && cmd != GETFL'
0.000 sssd_kcm/303828 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLK, arg: 0x7fffdc6a8a50)
0.013 sssd_kcm/303828 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLKW, arg: 0x7fffdc6a8aa0)
0.090 sssd_kcm/303828 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLKW, arg: 0x7fffdc6a88e0)
^Croot@number:~#
This picks up the changes in:
