Dear Linux kernel developers and maintainers:
We are writing to report a possible deadlock in
f2fs_invalidate_blocks, discovered with our modified version of
syzkaller.
This issue was initially found in kernel v6.17-rc5 (commit
76eeb9b8de9880ca38696b2fb56ac45ac0a25c6c). Unfortunately, we do not
yet have a stable C/Syz program to reproduce this deadlock. We are
currently analyzing the root cause and working to create a reliable
reproducer, which we will share as soon as it is available.
Attached are the kernel console output, .config file, and formatted
bug report for your analysis. Please let us know if any further
information would be helpful.
Best regards,
Jiaming Zhang
