#     kallsyms: ignore __kstrtab_* and __kstrtabns_* symbols
#     
#     Every EXPORT_SYMBOL creates __kstrtab_* and __kstrtabns_*, which
#     consumes 15-20% of the kallsyms entries.
#     
#     For 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
