Hi all, In v3 I rebased patches according upstream and removed already applied patches. Also in this revision I corrected 'Fixes' tag formatting, added corrections to Ext4GetUcs2DirentName to filter out directory entry names containing \0 as invalid and added a fix for building using MSVC.
This patchset fixes several code problems found by fuzzing Ext4Dxe like buffer and integer overflows, memory leaks, logic bugs and so on.
