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
