Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to do sanity check on sbi->total_valid_block_count
syzbot reported a f2fs bug as below:
------------[ cut here ]------------
kernel BUG at fs/f2fs/f2fs.h:2521!
RIP: 0010:dec_valid_block_count+0x3b2/0x3c0 fs/f2fs/f2fs.h:2521

do_syscall_64+0xf3/0x230 arch/x86/entry/syscall_64.c:94
The reason is: in fuzzed image, sbi->total_valid_block_count is
inconsistent w/ mapped blocks indexed by inode, so, we should
not trigger panic for such case, instead, let's print log and
set fsck flag.
