kallsyms: ignore __kstrtab_* and __kstrtabns_* symbols
Every EXPORT_SYMBOL creates __kstrtab_* and __kstrtabns_*, which consumes 15-20% of the kallsyms entries. For example, on the system built from the x86_64 defconfig, $ cat /proc/kallsyms | wc 129527 388581 5685465 $ cat /proc/kallsyms | grep __kstrtab | wc 23489 70467 1187932 We already ignore __crc_* symbols populated by EXPORT_SYMBOL, so it should be fine to ignore __kstrtab_* and __kstrtabns_* as well. This makes vmlinux a bit smaller. $ size vmlinux.before vmlinux.after text data bss dec hex filename 22785374 8559694 1413328 32758396 1f3da7c vmlinux.before 22785374 8137806 1413328 32336508 1ed6a7c vmlinux.after Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
