[RFC PATCH 0/3] kmemleak: Add support for the bootmem allocator

[Catalin Marinas <catalin.marinas@arm.com>]

Hi,

In the last few days, I went through of false positives reported by
kmemleak and it turns out some of them were caused by not tracking
alloc_bootmem* calls. Rather than adding more and more kmemleak
annotations throughout the kernel, I decided to add support for tracking
all the alloc_bootmem* and free_bootmem calls.

The latter may not have a corresponding alloc_bootmem* pair or it may
only free part of a block. I changed kmemleak to support this usage.

Thanks for your feedback.


Catalin Marinas (3):
      kmemleak: Remove alloc_bootmem annotations introduced in the past
      kmemleak: Add callbacks to the bootmem allocator
      kmemleak: Allow partial freeing of memory blocks
