From 663cb6340c6e84fe29aa6d0fa63d85ea6bd6cd19 Mon Sep 17 00:00:00 2001 From: Jackie Liu Date: Thu, 7 Mar 2019 16:30:10 -0800 Subject: scripts/gdb: replace flags (MS_xyz -> SB_xyz) Since commit 1751e8a6cb93 ("Rename superblock flags (MS_xyz -> SB_xyz)"), scripts/gdb should be updated to replace MS_xyz with SB_xyz. This change didn't directly affect the running operation of scripts/gdb until commit e262e32d6bde "vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled" removed the definitions used by constants.py. Update constants.py.in to utilise the new internal flags, matching the implementation at fs/proc_namespace.c::show_sb_opts. Note to stable, e262e32d6bde landed in v5.0-rc1 (which was just released), so we'll want this picked back to 5.0 stable once this patch hits mainline (akpm just picked it up). Without this, debugging a kernel a kernel via GDB+QEMU is broken in the 5.0 release.
