The other patch is a fix for sysfs object, we have a test for that and it leads to a crash. The other syzkaller reports are most likely races around device locking, we have a candidate fix that's been in the development queue. Some reports don't have a reproducer and validating the fix is not straightforward, I'll send another pull request once this is finished. Please pull, thanks. ---------------------------------------------------------------- The following changes since commit 1c78544eaa4660096aeb6a57ec82b42cdb3bfe5a: btrfs: fix wrong address when faulting in pages in the search ioctl (2020-09-14 17:27:16 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux.git for-5.9-rc6-tag for you to fetch changes up to b5ddcffa37778244d5e786fe32f778edf2bfc93e: btrfs: fix put of uninitialized kobject after seed device delete (2020-09-22 15:57:52 +0200) ---------------------------------------------------------------- Anand Jain (1): btrfs: fix put of uninitialized kobject after seed device delete Johannes Thumshirn (1): btrfs: fix overflow when copying corrupt csums for a message fs/btrfs/disk-io.c | 11 +++++------ fs/btrfs/sysfs.c | 16 ++++++++++------ 2 files changed, 15 insertions(+), 12 deletions(-)
