Subject: [PATCH v2 0/3] io_uring mm related abuses
Date: Tue, 24 Jun 2025 14:40:32 +0100 [thread overview]
Message-ID: <cover.1750771718.git.asml.silence@gmail.com> (raw)
Patch 1 uses unpin_user_folio instead of the page variant.
Patches 2-3 make sure io_uring doesn't make any assumptions
about user pointer alignments.
v2: change patch 1 tags
use folio_page_idx()
Pavel Begunkov (3):
io_uring/rsrc: fix folio unpinning
io_uring/rsrc: don't rely on user vaddr alignment
io_uring: don't assume uaddr alignment in io_vec_fill_bvec
