You are right. The commit id I sent was incorrect. I mistakenly used the git describe-style suffix g1d51b370a0f8, but the actual git commit is: 1d51b370a0f8f642f4fc84c795fbedac0fcdbbd2 The short commit id is: 1d51b370a0f8 Sorry for the confusion. I am also re-checking whether the kernel image was built from a clean tree and whether there were any local modifications when the crash was reproduced, so that the reported source line numbers match the exact build. Thanks. ------------------------------ *发件人:* David Hildenbrand (Arm) *发送时间:* 2026年4月21日 22:06 *收件人:* Zw Tang ; linux-mm@kvack.org ; akpm@linux-foundation.org ; hannes@cmpxchg.org < hannes@cmpxchg.org> *抄送:* kvm@vger.kernel.org ; linux-kernel@vger.kernel.org ; pbonzini@redhat.com ; seanjc@google.com < seanjc@google.com> *主题:* Re: [BUG] WARNING in workingset_activation triggered by KVM page fault path on Linux 7.0.0-08391-g1d51b370a0f8 On 4/21/26 13:17, Zw Tang wrote: > Hi, > > I am reporting a WARNING in workingset_activation() triggered by a > syzkaller C reproducer on Linux 7.0.0-08391-g1d51b370a0f8. g1d51b370a0f8 is not a known git commit id. Do you have an upstream git commit where the line number include/linux/memcontrol.h:381 makes sense? -- Cheers, David
