Subject: [GIT PULL] Btrfs fixes for 5.9-rc7

Hi,

syzkaller started to hit us with reports, in this pull request there's a
fix for one type (stack overflow when printing checksums on read error).
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.
