[PATCH] mm/huge_memory: drop beyond-EOF folios with the right number of refs.

by Zi Yan

When an after-split folio is large and needs to be dropped due to EOF, folio_put_refs(folio, folio_nr_pages(folio)) should be used to drop all page cache refs. Otherwise, the folio will not be freed, causing memory leak. This leak would happen on a filesystem with blocksize > page_size and a truncate is performed, where the blocksize makes folios split to >0 order ones, causing truncated folios not being freed. Fixes: c010d47f107f ("mm: thp: split huge page to any lower order pages") Reported-by: Hugh Dickins <hughd(a)google.com> Closes: https://lore.kernel.org/all/fcbadb7f-dd3e-21df-f9a7-2853b53183c4@google.com/ Cc: stable(a)vger.kernel.org Signed-off-by: Zi Yan <ziy(a)nvidia.com> --- mm/huge_memory.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/huge_memory.c b/mm/huge_memory.c index 3d3ebdc002d5..373781b21e5c 100644 --- a/mm/huge_memory.c +++ b/mm/huge_memory.c @@ -3304,7 +3304,7 @@ static void __split_huge_page(struct page *page, struct list_head *list, folio_account_cleaned(tail, inode_to_wb(folio->mapping->host)); __filemap_remove_folio(tail, NULL); - folio_put(tail); + folio_put_refs(tail, folio_nr_pages(tail)); } else if (!folio_test_anon(folio)) { __xa_store(&folio->mapping->i_pages, tail->index, tail, 0); -- 2.47.2

net: cadence: macb: Enable software IRQ coalescing by default

by Daniel J Blueman

The macb ethernet driver (Raspberry Pi 5) delivers interrupts only to the first core, quickly saturating it at higher packet rates. Introducing software interrupt coalescing dramatically alleviates this limitation; the oneliner fix is upstream at d57f7b45945ac0517ff8ea50655f00db6e8d637c. Please backport this fix to 6.6 -stable to bring this benefit to more Raspberry Pis; it applies cleanly on this branch. Many thanks, Daniel -- Daniel J Blueman

[PATCH v3 2/2] phy: freescale: imx8m-pcie: assert phy reset and perst in power off

by Stefan Eichenberger

From: Stefan Eichenberger <stefan.eichenberger(a)toradex.com> Ensure the PHY reset and perst is asserted during power-off to guarantee it is in a reset state upon repeated power-on calls. This resolves an issue where the PHY may not properly initialize during subsequent power-on cycles. Power-on will deassert the reset at the appropriate time after tuning the PHY parameters. During suspend/resume cycles, we observed that the PHY PLL failed to lock during resume when the CPU temperature increased from 65C to 75C. The observed errors were: phy phy-32f00000.pcie-phy.3: phy poweron failed --> -110 imx6q-pcie 33800000.pcie: waiting for PHY ready timeout! imx6q-pcie 33800000.pcie: PM: dpm_run_callback(): genpd_resume_noirq+0x0/0x80 returns -110 imx6q-pcie 33800000.pcie: PM: failed to resume noirq: error -110 This resulted in a complete CPU freeze, which is resolved by ensuring the PHY is in reset during power-on, thus preventing PHY PLL failures.
