Messages in this thread Patch in this message | | | From | Prarit Bhargava <> | Subject | [PATCH] Makefile, CONFIG_MODVERSIONS, ignore *.mod.c files | Date | Wed, 5 Feb 2014 10:01:51 -0500 |
| |
CONFIG_MODVERSIONS=y results in a .mod.c for every compiled file in the kernel. Issuing a 'make cscope' on a compiled kernel tree results in the cscope files containing *.mod.c files.
[prarit@prarit linux]# make cscope [prarit@prarit linux]# cat cscope.files | grep mod.c | wc -l 4807
These files are not useful for cscope and should be ignored. For example,
# line filename / context / line 1 105 arch/x86/kvm/kvm-intel.mod.c <<GLOBAL>> { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) }, 2 508 drivers/block/mtip32xx/mtip32xx.h <<GLOBAL>> int numa_node; 3 55 drivers/block/mtip32xx/mtip32xx.mod.c <<GLOBAL>> { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) }, 4 37 drivers/cpufreq/acpi-cpufreq.mod.c <<GLOBAL>> { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) }, <snip>
Add *.mod.c to the RCS_FIND_IGNORE in the top-level Makefile and to the ignore list in scripts/tags.sh.
