*主题:* 回复: [BUG] WARNING in workingset_activation triggered by KVM page
fault path on Linux 7.0.0-08391-g1d51b370a0f8
Hi David,
Thanks for pointing this out.
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.

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?
