Update bits/mman.h constants and tst-mman-consts.py for Linux 5.3.
|
|
|
520cc8 |
|
|
|
520cc8 |
The Linux 5.3 uapi headers have some rearrangement relating to MAP_*
|
|
|
520cc8 |
constants, which includes the effect of adding definitions of MAP_SYNC
|
|
|
520cc8 |
on powerpc and sparc. This patch updates the corresponding glibc
|
|
|
520cc8 |
bits/mman.h headers accordingly, and updates the Linux kernel version
|
|
|
520cc8 |
number in tst-mman-consts.py to reflect that these constants are now
|
|
|
520cc8 |
current with that kernel version.
|
|
|
520cc8 |
|
|
|
520cc8 |
Tested with build-many-glibcs.py.

* sysdeps/unix/sysv/linux/powerpc/bits/mman.h [__USE_MISC]
|
|
|
520cc8 |
(MAP_SYNC): New macro.
|
|
|
520cc8 |
* sysdeps/unix/sysv/linux/sparc/bits/mman.h [__USE_MISC]
|
|
|
520cc8 |
(MAP_SYNC): Likewise.
|
|
|
520cc8 |
* sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Update Linux
|
|
|
520cc8 |
kernel version number to 5.3.
