Subject: [PATCH 0/3] Type aware module allocator
Date: Thu, 25 May 2023 22:15:26 -0700 [thread overview]
Message-ID: <20230526051529.3387103-1-song@kernel.org> (raw)
This set implements the second part of module type aware allocator
(module_alloc_type), which was discussed in [1]. This part contains the
interface of the new allocator, as well as changes in x86 code to use the
new allocator (modules, BPF, ftrace, kprobe).
The set does not contain a binpack allocator to enable sharing huge pages
among different allocations. But this set defines the interface used by
the binpack allocator. [2] has some discussion on different options of the
binpack allocator.
