could you exlictly point to two commit-id?
sure
this patch 8be7258a: mseal: add mseal syscall ff388fe5c: mseal: wire up mseal syscall
I failed to apply this patch set to "8be7258a: mseal: add mseal syscall"
look your patch set again [PATCH v1 1/2] mseal:selftest mremap across VMA boundaries just for kselftests
and I can apply [PATCH v1 2/2] mseal: refactor mremap to remove can_modify_mm upon "8be7258a: mseal: add mseal syscall" cleanly
so I will start test for this [PATCH v1 2/2]
BTW, I will firstly use our default setting - "60s testtime; reboot between each run; run 10 times", since we've already have the data for 8be7258a and ff388fe5c then we could give you an update kind of quickly.
as some private mail discussed, you want some special run method, could you elaborate them here? thanks
here is a quick update before you give us more details about special run method.
by our default run method (60s testtime; reboot between each run; run 10 times), your "[PATCH v1 2/2] mseal: refactor mremap to remove can_modify_mm" could resolve regression partically.

to avoid the impact of other changes, better to apply the patch upon 8be7258a directly.
if you prefer other base for this patch, please let us know. then we will supply the results for 4 commits in fact:
this patch the base of this patch 8be7258a: mseal: add mseal syscall ff388fe5c: mseal: wire up mseal syscall
Thank you for your time and assistance in helping me on understanding this issue.
due to resource constraint, please expect that we need several days to finish this test request.
No problem.
Thanks for your help! -Jeff
