[This email was generated by a script. Let me know if you have any suggestions to make it better, or if you want it re-generated with the latest status.] Of the currently open syzbot reports against the upstream kernel, I've manually marked 11 of them as possibly being bugs in the block subsystem. I've listed these reports below, sorted by an algorithm that tries to list first the reports most likely to be still valid, important, and actionable. Of these 11 bugs, 3 were seen in mainline in the last week. If you believe a bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at https://goo.gl/tpsmEJ#status If you believe I misattributed a bug to the block subsystem, please let me know, and if possible forward the report to the correct people or mailing list. Here are the bugs: -------------------------------------------------------------------------------- Title: KASAN: use-after-free Read in debugfs_remove (3) Last occurred: 1 day ago Reported: 286 days ago Branches: Mainline and others Dashboard link: https://syzkaller.appspot.com/bug?id=6d5c55bc531f0ef83e8faca014cc123b4498f7a6 Original thread: https://lkml.kernel.org/lkml/000000000000140c370577db5ece@xxxxxxxxxx/T/#u This bug has a C reproducer.
