In the Linux kernel, the following vulnerability has been resolved:
btrfs: do not WARN_ON() if we have PageError set
Whenever we do any extent buffer operations we call
assert_eb_page_uptodate() to complain loudly if we're operating on an
non-uptodate page. Our overnight tests caught this warning earlier this
week
