In most of the cases, a static symbol marked for # exporting is an odd combination that should be fixed either by deleting # the exporting mark or by removing the static attribute and adding the # appropriate declaration to headers. # # This check could help to detect the following problems: # 1. 550113d4e9f5 ("i2c: add newly exported functions to the header, too") # 2. 54638c6eaf44 ("net: phy: make exported variables non-static") # 3. 98ef2046f28b ("mm: remove the exporting of totalram_pages") # 4. 73df167c819e ("s390/zcrypt: remove the exporting of ap_query_configuration") # 5. a57caf8c527f ("sunrpc/cache: remove the exporting of cache_seq_next") # 6. e4e4730698c9 ("crypto: skcipher - remove the exporting of skcipher_walk_next") # 7. 14b4c48bb1ce ("gve: Remove the exporting of gve_probe") # 8. 9b79ee9773a8 ("scsi: libsas: remove the exporting of sas_wait_eh") # 9. ... # # Build time impact, allmodconfig, Dell XPS 15 9570 (measurements 3x): # $ make mrproper; make allmodconfig; time make -j12; \ # git checkout HEAD~1; \ # make mrproper; make allmodconfig; time make -j12 # 1. # (with patch) 17635,94s user 1895,54s system 1085% cpu 29:59,22 total # (w/o patch) 17275,42s user 1803,87s system 1112% cpu 28:35,66 total # 2. # (with patch) 17369,51s user 1763,28s system 1111% cpu 28:41,47 total # (w/o patch) 16880,50s user 1670,93s system 1113% cpu 27:46,56 total # 3. # (with patch) 17937,88s user 1842,53s system 1109% cpu 29:42,26 total # (w/o patch) 17267,55s user 1725,09s system 1111% cpu 28:28,17 total # # Thus, the current implementation adds approx. 1 min for allmodconfig. # # Acked-by: Emil Velikov <emil.l.velikov@gmail.com> # Signed-off-by: Denis Efremov <efremov@linux.com> # Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 1a288d0d920dfb9747bbefc8d601a971885f470f # < make -s -j 120 ARCH=sparc64 O=/kisskb/build/kbuild_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 120 ARCH=sparc64 O=/kisskb/build/kbuild_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
