I've backported fixes for several security issues involving filesystem validation in f2fs.  All of these are already fixed in the later stable branches.

I tested with the reproducers where available.  I also checked for regressions with xfstests and didn't find any (but many tests fail with or without these changes).

Thanks for all of these, now queued up.

Note, one of these, d4fdf8ba0e58 ("f2fs: fix a panic caused by NULL flush_cmd_control"), was already in the 4.4.169 release.

Sorry about that - it took me some time to prepare and test these and I was starting from a base of 4.4.167.

Ben.
