Regression in 4.14.147, 4.19.76, 5.2.18 leading to kernel panic on btrfs root fs mount

by Andrew Macks

Was not sure the correct way to escalate this quickly enough. I unfortunately discovered this issue while upgrading a server (remotely) to 4.19.78 (longterm). *Bug 205181* <https://bugzilla.kernel.org/show_bug.cgi?id=205181> - kernel panic when accessing btrfs root device with f2fs in kernel https://bugzilla.kernel.org/show_bug.cgi?id=205181 Andrew.

[PATCH v4 2/3] powerpc: Avoid clang warnings around setjmp and longjmp

by Nathan Chancellor

Commit aea447141c7e ("powerpc: Disable -Wbuiltin-requires-header when setjmp is used") disabled -Wbuiltin-requires-header because of a warning about the setjmp and longjmp declarations. r367387 in clang added another diagnostic around this, complaining that there is no jmp_buf declaration. In file included from ../arch/powerpc/xmon/xmon.c:47: ../arch/powerpc/include/asm/setjmp.h:10:13: error: declaration of built-in function 'setjmp' requires the declaration of the 'jmp_buf' type, commonly provided in the header <setjmp.h>. [-Werror,-Wincomplete-setjmp-declaration] extern long setjmp(long *); ^ ../arch/powerpc/include/asm/setjmp.h:11:13: error: declaration of built-in function 'longjmp' requires the declaration of the 'jmp_buf' type, commonly provided in the header <setjmp.h>. [-Werror,-Wincomplete-setjmp-declaration] extern void longjmp(long *, long); ^ 2 errors generated. We are not using the standard library's longjmp/setjmp implementations for obvious reasons; make this clear to clang by using -ffreestanding on these files.

[for-linus][PATCH 10/11] tracing/hwlat: Dont ignore outer-loop duration when calculating max_latency

by Steven Rostedt

From: "Srivatsa S. Bhat (VMware)" <srivatsa(a)csail.mit.edu> max_latency is intended to record the maximum ever observed hardware latency, which may occur in either part of the loop (inner/outer).

[for-linus][PATCH 09/11] tracing/hwlat: Report total time spent in all NMIs during the sample

by Steven Rostedt

From: "Srivatsa S. Bhat (VMware)" <srivatsa(a)csail.mit.edu> nmi_total_ts is supposed to record the total time spent in *all* NMIs that occur on the given CPU during the (active portion of the) sampling window. However, the code seems to be overwriting this variable for each NMI, thereby only recording the time spent in the most recent NMI. Fix it by accumulating the duration instead.

❌ FAIL: Test report for kernel 5.4.0-rc2-71e7fa7.cki (stable-next)

by CKI Project

Hello, We ran automated tests on a recent commit from this kernel tree: Kernel repo: git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux-stable.git Commit: 71e7fa7873ec - Merge branch 'stable-next' of ssh://chubbybox:/home/sasha/data/next into stable-next The results of these automated tests are provided below. Overall result: FAILED (see details below) Merge: OK Compile: FAILED All kernel binaries, config files, and logs are available for download here: https://artifacts.cki-project.org/pipelines/222115 We attempted to compile the kernel for multiple architectures, but the compile failed on one or more architectures: aarch64: FAILED (see build-aarch64.log.xz attachment) ppc64le: FAILED (see build-ppc64le.log.xz attachment) s390x: FAILED (see build-s390x.log.xz attachment) x86_64: FAILED (see build-x86_64.log.xz attachment) We hope that these logs can help you find the problem quickly. For the full detail on our testing procedures, please scroll to the bottom of this message. Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective. ,-. ,-.

[PATCH] btrfs: don't needlessly create extent-refs kernel thread

by David Sterba

The patch 32b593bfcb58 ("Btrfs: remove no longer used function to run delayed refs asynchronously") removed the async delayed refs but the thread has been created, without any use. Remove it to avoid resource consumption.
