[xenial CVE-2015-8952 0/3] replace mbcache with mbcache2 for ext2/ext4

[Thadeu Lima de Souza Cascardo]

Third patch needed backport because of context due to commit
c6d5612f80923170dad06c04736984cc9bcc8568 ("ext4: lock the xattr block before checksuming it").

Removal of old mbcache was not included to minimize number of patches.

Jan Kara (3):
  mbcache2: reimplement mbcache
  ext2: convert to mbcache2
  ext4: convert to mbcache2
