From e5ebffe18e5add85acb23c7a0f74509749967204 Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Sun, 19 Jul 2020 17:10:45 -0600 Subject: [PATCH] dyndbg: rename __verbose section to __dyndbg dyndbg populates its callsite info into __verbose section, change that to a more specific and descriptive name, __dyndbg. Also, per checkpatch: simplify __attribute(..) to __section(__dyndbg) declaration. and 1 spelling fix, decriptor Acked-by: Signed-off-by: Jim Cromie Link: https://lore.kernel.org/r/20200719231058.1586423-6-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman --- include/asm-generic/vmlinux.lds.h | 6 +++--- include/linux/dynamic_debug.h | 4 ++-- kernel/module.c | 2 +- lib/dynamic_debug.c | 12 ++++++------ 4 files changed, 12 insertions(+), 12 deletions(-) diff --git a/include/asm-generic/vmlinux.lds.h b/include/asm-generic/vmlinux.lds.h index db600ef218d7..05af5cef1ad6 100644 --- a/include/asm-generic/vmlinux.lds.h +++ b/include/asm-generic/vmlinux.lds.h @@ -320,9 +320,9 @@ *(__tracepoints) \ /* implement dynamic printk debug */ \ . = ALIGN(8); \ - __start___verbose = .; \ - KEEP(*(__verbose)) \ - __stop___verbose = .; \ + __start___dyndbg = .; \ + KEEP(*(__dyndbg)) \ + __stop___dyndbg = .; \ LIKELY_PROFILE() \ BRANCH_PROFILE() \ TRACE_PRINTKS() \ diff --git a/include/linux/dynamic_debug.h b/include/linux/dynamic_debug.h index abcd5fde30eb..aa9ff9e1c0b3 100644 --- a/include/linux/dynamic_debug.h +++ b/include/linux/dynamic_debug.h @@ -80,7 +80,7 @@ void __dynamic_ibdev_dbg(struct _ddebug *descriptor, #define DEFINE_DYNAMIC_DEBUG_METADATA(name, fmt) \ static struct _ddebug __aligned(8) \ - __attribute__((section("__verbose"))) name = { \ + __section(__dyndbg) name = { \ .modname = KBUILD_MODNAME, \ .function = __func__, \ .filename = __FILE__, \ @@ -133,7 +133,7 @@ void __dynamic_ibdev_dbg(struct _ddebug *descriptor, /* * "Factory macro" for generating a call to func, guarded by a - * DYNAMIC_DEBUG_BRANCH.
