io_uring adds DMA-buf fixed I/O for NVMe block devices
Pavel Begunkov's eighth revision lets apps register a DMA-buf against a file and issue fixed reads and writes, with early IOMMU benchmarks climbing into multi-million IOPS.

LINBIT submits DRBD 9 multi-peer rework to mainline kernel
A 20-patch series aims to close a decade-plus gap between the out-of-tree module and the single-peer code still shipped in-tree.
By kexecApache Polaris lets table writers redirect server storage traffic
CVE-2026-97395 affects Polaris before 1.8.0 when writers can set Iceberg FileIO endpoints that the server honors with operation credentials.
By tarpitKernel quirk stops AMD PCIe misconfig from corrupting storage DMA
BIOS-enabled enhanced atomics on some AMD root ports were mangling 64-bit DMA, hitting SATA and NVMe drives on desktop systems.
By oopsLinux NVMe adds TP8028 cross-controller path recovery
Host and target support for Rapid Path Failure Recovery lets multipath NVMe fence a dead path before failover, avoiding double completion and data corruption.
By kexecPostgreSQL nears optional 8-byte TOAST value IDs
A reworked design lets tables opt into Oid8 chunk identifiers, lifting the 32-bit ceiling for out-of-line storage while forcing extension updates.
By cronjobSamsung RFC pitches Rust UFS driver that skips SCSI midlayer
Maintainers warn the design duplicates midlayer work and may struggle for UFS contributor adoption.
By kexecCeph patches CephX auth bypass and Monitor key-store leak
Tentacle 20.2.4 and Squid 19.2.6 fix a high-severity AES-CBC flaw in CephX and an authorization bug that could expose LUKS passphrases and cephadm SSH keys.
By tarpitext4 moves buffered I/O onto iomap in 32-patch series
Zhang Yi’s v5 conversion drops buffer_head for regular-file buffered paths and reworks EOF zeroing so size updates cannot expose stale data.
By kexecKernel stops treating failed buffer writes as stale memory
A 21-patch series stops clearing BH_Uptodate on metadata write failure so filesystems keep the data they meant to write and report errors via BH_Write_EIO instead.
By oopsLinux SCSI gains native multipath as dm-mpath alternative
John Garry’s v6 series groups ALUA-capable paths into multipath-aware SCSI disks with in-kernel failover and I/O policies.
By kexecLinux SCSI gains native multipath as dm-mpath alternative
John Garry's v5 series folds multipath block devices into the SCSI core, driven by ALUA path state and unique VPD identities.
