Hello,

syzbot found the following issue on:

HEAD commit: 85cfd6e539bd kmsan: core: delete kmsan_gup_pgd_range()
git tree: https://github.com/google/kmsan.git master
console output: https://syzkaller.appspot.com/x/log.txt?x=12d6c53c700000

Based off a previous patch to fix a similar issue.
-------------------------

Looks sane.

Can you, please, send it as proper patch with explanation in commit 
message and with a bit cutted log, since full ->probe() calltrace is not 
interesting :)




With regards,
