Thanks!
Yes I have already seen this and even one more.
https://www.programmersought.com/article/31513579159/

But I think these changes are not yet in the mainline right ?

So, I wanted to know which are the exact patches which are already
accepted in mainline ?
Or, is it already mainlined ?

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/fs/squashfs?h=next-20210611
From here, I see that we are only till this:
==> 2018-08-02: Squashfs: Compute expected length from inode size
rather than block length


Thanks,
