#     Merge tag 'Wstringop-overflow-for-6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux
#     
#     Pull stringop-overflow warning update from Gustavo A. R. Silva:
#      "Enable -Wstringop-overflow globally.
#     
#       I waited for the release of -rc1 to run a final build-test on top of
#       it before sending this pull request. Fortunatelly, after building 358
#       kernels overnight (basically all supported archs with a wide variety
#       of configs), no more warnings have surfaced! :)
#     
#       Thus, we are in a good position to enable this compiler option for all
#       versions of GCC that support it, with the exception of GCC-11, which
#       appears to have some issues with this option [1]"
