[PATCH v5 0/2] mm, treewide: Rename kzfree() to kfree_sensitive()
v5:
- Break the btrfs patch out as a separate patch to be processed
independently.
- Update the commit log of patch 1 to make it less scary.
- Add a kzfree backward compatibility macro in patch 2.
v4:
- Break out the memzero_explicit() change as suggested by Dan Carpenter
so that it can be backported to stable.
- Drop the "crypto: Remove unnecessary

v4:
- Break out the memzero_explicit() change as suggested by Dan Carpenter
so that it can be backported to stable.
- Drop the "crypto: Remove unnecessary memzero_explicit()" patch for
now as there can be a bit more discussion on what is best. It will be
introduced as a separate patch later on after this one is merged.

[PATCH 0/2] mm, treewide: Rename kzfree() to kfree_sensitive()
This patchset makes a global rename of the kzfree() to kfree_sensitive()
to highlight the fact buffer clearing is only needed if the data objects
contain sensitive information like encrpytion key. The fact that kzfree()
uses memset() to do the clearing isn't totally safe either as compiler
may compile out the clearing in their optimizer. Instead, the new
kfree_sensitive() uses
