It was not due to races and lack of barriers in the end. (Harry Yoo) - Fix for severe performance regression due to unnecessary sheaf refill restrictions exposed by mempool allocation strategy. (Vlastimil Babka) - Stable fix for potential silent percpu sheaf flushing failures on PREEMPT_RT. (Vlastimil Babka) ---------------------------------------------------------------- The following changes since commit e9217ca77dc35b4978db0fe901685ddb3f1e223a: mm/slab: initialize slab->stride early to avoid memory ordering issues (2026-02-27 16:22:57 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-7.0-rc2 for you to fetch changes up to 6432f15c818cb30eec7c4ca378ecdebd9796f741: mm/slab: change stride type from unsigned short to unsigned int (2026-03-04 11:05:57 +0100) ---------------------------------------------------------------- slab fixes for 7.0-rc2 ---------------------------------------------------------------- Harry Yoo (1): mm/slab: change stride type from unsigned short to unsigned int Vlastimil Babka (1): slab: distinguish lock and trylock for sheaf_flush_main() Vlastimil Babka (SUSE) (1): mm/slab: allow sheaf refill if blocking is not allowed mm/slab.h | 10 ++++----- mm/slub.c | 69 +++++++++++++++++++++++++++++++++++++++++++-------------------- 2 files changed, 52 insertions(+), 27 deletions(-)
