Hi, my crisv32 qemu test fails with next-20150917 as follows. NET: Registered protocol family 16 kernel BUG at mm/slab.c:1648! Linux 4.3.0-rc1-next-20150917 #1 Wed Sep 16 23:56:59 PDT 2015 Oops: 0000 [ register dump follows ] See http://server.roeck-us.net:8010/builders/qemu-crisv32-next/builds/83/steps/qemubuildcommand/logs/stdio for a complete log. Bisect points to 'page-flags: define behavior SL*B-related flags on compound pages'. One of the bisect steps, at 'mm: support madvise(MADV_FREE)', causes a build failure, but that did not seem to affect the overall bisect results. Just for completeness, here is the reported build failure. mm/vmscan.c: In function ‘shrink_page_list’: mm/vmscan.c:1093:5: error: implicit declaration of function ‘__clear_page_locked’ [-Werror=implicit-function-declaration] __clear_page_locked(page); ^ Guenter --- Bisect log: # bad: [01c8787d7f7ea56c16d94cf7133022189be231ad] Add linux-next specific files for 20150917 # good: [6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f] Linux 4.3-rc1 git bisect start 'HEAD' 'v4.3-rc1' # good: [5b986ec423c0e7615824a46b48e6d5cfa45ac82d] Merge remote-tracking branch 'battery/master' git bisect good 5b986ec423c0e7615824a46b48e6d5cfa45ac82d # good: [d4cb33477f815c8a0c8b1c28e986c79d89d37491] Merge remote-tracking branch 'staging/staging-next' git bisect good d4cb33477f815c8a0c8b1c28e986c79d89d37491 # good: [b73c6555e0733dc811d6f7b533183c518d6c7bb2] Merge remote-tracking branch 'livepatching/for-next' git bisect good b73c6555e0733dc811d6f7b533183c518d6c7bb2 # good: [5c74cd46dcbc65a682b2bdfc74d51feac91c0e0f] mm-introduce-vm_lockonfault-v9 git bisect good 5c74cd46dcbc65a682b2bdfc74d51feac91c0e0f # bad: [b928350d7f112a2525516c444ebac84ed53e937e] mm: support madvise(MADV_FREE) git bisect bad b928350d7f112a2525516c444ebac84ed53e937e # good: [8129659afb03679ae08e6bc862c78bc571a10170] page-flags-introduce-page-flags-policies-wrt-compound-pages-fix git bisect good 8129659afb03679ae08e6bc862c78bc571a10170 # bad: [f285037c71068de549f2432c9d275844575707de] page-flags: look at head page if the flag is encoded in page->mapping git bisect bad f285037c71068de549f2432c9d275844575707de # bad: [ceba84a8eac816c92d1f1789b1273f812ac9af80] page-flags: define PG_reserved behavior on compound pages git bisect bad ceba84a8eac816c92d1f1789b1273f812ac9af80 # good: [40774838143f84a5c38ecee2f142bbd6b9a0687a] page-flags: define behavior of LRU-related flags on compound pages git bisect good 40774838143f84a5c38ecee2f142bbd6b9a0687a # bad: [fcd079cce0714accc45d35ffad59bf05ddb37893] page-flags: define behavior of Xen-related flags on compound pages git bisect bad fcd079cce0714accc45d35ffad59bf05ddb37893 # bad: [2c42f049fc7aa8198514707bce436c7f9f2c318f] page-flags: define behavior SL*B-related flags on compound pages git bisect bad 2c42f049fc7aa8198514707bce436c7f9f2c318f # first bad commit: [2c42f049fc7aa8198514707bce436c7f9f2c318f] page-flags: define behavior SL*B-related flags on compound pages -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
