  • 9078370c0   kmemleak: Add support for NO_BOOTMEM configurations ... Browse Code »

    With commits 08677214 and 59be5a8e, alloc_bootmem()/free_bootmem() and
    friends use the early_res functions for memory management when
    NO_BOOTMEM is enabled. This patch adds the kmemleak calls in the
    corresponding code paths for bootmem allocations.

  • eed63519e   x86: Do not free zero sized per cpu areas ... Browse Code »

    This avoids an infinite loop in free_early_partial().

    Add a warning to free_early_partial() to catch future problems.

    -v5: put back start > end back into WARN_ONCE()
    -v6: use one line for warning, suggested by Linus
    -v7: more tests
    -v8: remove the function name as suggested by Johannes
    WARN_ONCE() will print out that function name.

  • dce46a04d   early_res: Need to save the allocation name in drop_range_partial() ... Browse Code »

    During free_early_partial(), reserve_early_without_check() could end
    extending the early_res area from __check_and_double_early_res(); as a
    result, the location of the name for the current reservation could
    change.

    Therefore, we need to save a local copy of the name.
