[PATCH v8 00/21] Add zpdesc memory descriptor for zswap.zpool

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

I've updated this patchset for 6.13-rc1 because it's needed to eliminate
page->index, which I'm hoping to do in the next merge window.

 - Renamed mops to movable_ops and changed its type to unsigned long
 - Separated out the documentation of the individual page flags
 - Removed memcg_data again
 - Adapted to memcpy_from_page() API
 - Add kmap_local_zpdesc() instead of zpdesc_kmap_atomic()

My actual review of this has been quite limited.
