  • f21838e05   mm: cma: mark cma_bitmap_maxno() inline in header ... Browse Code »

    cma_bitmap_maxno() was marked as static and not static inline, which can
    cause warnings about this function not being used if this file is included
    in a file that does not call that function, and violates the conventions
    used elsewhere. The two options are to move the function implementation
    back to mm/cma.c or make it inline here, and it's simple enough for the
    latter to make sense.

    Provides a userspace interface to trigger a CMA allocation.

    Usage:

    echo [pages] > alloc

    This would provide testing/fuzzing access to the CMA allocation paths.

    I've noticed that there is no interfaces exposed by CMA which would let me
    fuzz what's going on in there.

    This small patchset exposes some information out to userspace, plus adds
    the ability to trigger allocation and freeing from userspace.

    This patch (of 3):

    Implement a simple debugfs interface to expose information about CMA areas
    in the system.

    Useful for testing/sanity checks for CMA since it was impossible to
    previously retrieve this information in userspace.
