Milk-V Jupiter Linux kernel
b77d5b1b83
Most callers of memcg_slab_free_hook() already know the slab, which could be passed to memcg_slab_free_hook() directly to reduce the overhead of an another call of virt_to_slab(). For bulk freeing of objects, the call of slab_objcgs() in the loop in memcg_slab_free_hook() is redundant as well. Rework memcg_slab_free_hook() and build_detached_freelist() to reduce those unnecessary overhead and make memcg_slab_free_hook() can handle bulk freeing in slab_free(). Move the calling site of memcg_slab_free_hook() from do_slab_free() to slab_free() for slub to make the code clearer since the logic is weird (e.g. the caller need to judge whether it needs to call memcg_slab_free_hook()). It is easy to make mistakes like missing calling of memcg_slab_free_hook() like fixes of: commit |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
