Merge tag 'kmemleak-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux

Trivial kmemleak bug-fixes:

 - Early logging doesn't stop when kmemleak is off by default.
 - Zero-size scanning areas should be ignored (currently it prints a
   warning).

* tag 'kmemleak-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux:
  kmemleak: Disable early logging when kmemleak is off by default
  kmemleak: Only scan non-zero-size areas
