  ext4: force revalidation of directory pointer after seekdir(2) (2018-04-01 23:21:03 -0400)

----------------------------------------------------------------
Cleanups and bugfixes for ext4, including some fixes to make ext4 more
robust against maliciously crafted file system images.  (I still don't
recommend that container folks hold any delusions that mounting
arbitary images that can be crafted by malicious attackers should be
considered sane thing to do, though!)
