[PATCH v1] scripts/gdb: fix parsing of MNT_* constants

From: Tony Ambardar
Date: Sun Jun 01 2025 - 01:50:47 EST


Recently, constants in linux/mount.h were changed from integer macros
parsable by LX_VALUE() to enums which are not, thus breaking gdb python
scripts:

Reading symbols from vmlinux...
Traceback (most recent call last):
File ".../linux/vmlinux-gdb.py", line 25, in <module>
import linux.constants
File ".../linux/scripts/gdb/linux/constants.py", line 19, in <module>
LX_MNT_NOSUID = MNT_NOSUID
NameError: name 'MNT_NOSUID' is not defined

Update to parse with LX_GDBPARSED(), which correctly handles enums.

Fixes: 101f2bbab541 ("fs: convert mount flags to enum")
