From mboxrd@z Thu Jan 1 00:00:00 1970 From: Steven Rostedt Date: Sat, 22 Dec 2018 16:20:07 +0000 Subject: [for-next][PATCH 0/5] tracing: Add string_has_prefix() and usages Message-Id: <20181222162007.697862256@goodmis.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-kernel@vger.kernel.org Cc: Ingo Molnar , Andrew Morton , Joe Perches , Namhyung Kim , Linus Torvalds , Yoshinori Sato , Rich Felker , linux-sh@vger.kernel.org I hope everyone is OK with these changes. I pushed to linux-next but I'm willing to change them if there are still issues. They ran through all my tests, althought zero-day-bot had a weird build regression in sh, that looks totally unrelated: Regressions in current branch: arch/sh/kernel/dwarf.c:107:26: error: 'dwarf_frame_reg' defined but not used [-Werror=unused-function] arch/sh/kernel/dwarf.c:1209:0: error: unterminated argument list invoking macro "WARN_ON" arch/sh/kernel/dwarf.c:226:12: error: 'dwarf_read_encoded_value' defined but not used [-Werror=unused-function] arch/sh/kernel/dwarf.c:306:26: error: 'dwarf_lookup_cie' defined but not used [-Werror=unused-function] arch/sh/kernel/dwarf.c:38:27: error: 'dwarf_frame_cachep' defined but not used [-Werror=unused-variable] arch/sh/kernel/dwarf.c:399:12: error: 'dwarf_cfa_execute_insns' defined but not used [-Werror=unused-function] arch/sh/kernel/dwarf.c:41:27: error: 'dwarf_reg_cachep' defined but not used [-Werror=unused-variable] arch/sh/kernel/dwarf.c:580:22: error: unused variable 'frame' [-Werror=unused-variable] arch/sh/kernel/dwarf.c:581:20: error: unused variable 'cie' [-Werror=unused-variable] arch/sh/kernel/dwarf.c:582:20: error: unused variable 'fde' [-Werror=unused-variable] arch/sh/kernel/dwarf.c:583:20: error: unused variable 'reg' [-Werror=unused-variable] arch/sh/kernel/dwarf.c:584:16: error: unused variable 'addr' [-Werror=unused-variable] arch/sh/kernel/dwarf.c:622:3: error: expected ';' at end of input arch/sh/kernel/dwarf.c:622:3: error: expected declaration or statement at end of input arch/sh/kernel/dwarf.c:622:3: error: 'WARN_ON' undeclared (first use in this function); did you mean 'WMARK_LOW'? Pushing to my for-next branch should kick off another run. Let's see if it reports that again.
