| |
When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which also depends on the modules name in Makefile. Refer to the information in "scripts/Makefile.lib":
# $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will # end up in (or would, if it gets compiled in) # Note: Files that end up in two or more modules are compiled without the # KBUILD_MODNAME definition. The reason is that any made-up name would # differ in different configs.
File "inet_connection_sock.h" is a common share header that not can be use for one module, so use pr_devel instead of pr_debug is OK.
