In the Linux kernel, the following vulnerability has been resolved:
f2fs: get rid of online repaire on corrupted directory
syzbot reports a f2fs bug as below:

Online repaire on corrupted directory in f2fs_lookup() can generate
dirty data/meta while racing w/ readonly remount, it may leave dirty
inode after filesystem becomes readonly, however, checkpoint() will
skips flushing dirty inode in a state of readonly mode, result in
above panic.
Let's get rid of online repaire in f2fs_lookup(), and leave the work
to fsck.f2fs.
