After f15afbd34d8f ("fs: fix undefined behavior in bit shift for
SB_NOUSER") the constants were changed from plain integers which
LX_VALUE() can parse to constants using the BIT() macro which causes the
following:
Reading symbols from build/linux-custom/vmlinux...done.
Traceback (most recent call last):
File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/vmlinux-gdb.py", line 25, in <module>
import linux.constants
File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/scripts/gdb/linux/constants.py", line 5
LX_SB_RDONLY = ((((1UL))) << (0))
Use LX_GDBPARSED() which does not suffer from that issue.
