Since commit 1751e8a6cb93 ("Rename superblock flags (MS_xyz -> SB_xyz)"), script/gdb need replace MS_xyz to SB_xyz.
Fix follow problem: root@localhost:/data# gdb -q vmlinux Reading symbols from vmlinux...done. Traceback (most recent call last): File "/data/vmlinux-gdb.py", line 32, in <module> import linux.proc File "/data/scripts/gdb/linux/proc.py", line 15, in <module> from linux import constants File "/data/scripts/gdb/linux/constants.py", line 2, in <module> LX_SB_RDONLY = MS_RDONLY NameError: name 'MS_RDONLY' is not defined (gdb)
