[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
