Linux Kernel Daily: SCSI Layer Hardens Against Unsafe Locking
Martin Petersen's SCSI pull for the 7.3 merge window centers on enabling compiler-based context analysis across the SCSI core and UFS, backed by a wave of lock annotation work and a cleanup of legacy string functions in the lpfc driver.

Good day. It's August 30th, 2026, and this is Linux Kernel Daily.
Today's signal comes from one merged pull request that folds in twenty-six commits, and the throughline is defensive engineering: making the SCSI subsystem provably correct rather than just functionally correct.
The headline item is context analysis, now enabled for the SCSI core and UFS. This is a compiler-assisted check that verifies lock usage at build time. Commit series in this pull add lock context annotations to the SCSI core, protect host state changes with the host lock explicitly, and pass the SCSI host pointer…
The second theme is string-handling cleanup in the lpfc Fibre Channel driver. Multiple commits strip out the deprecated strlcat function, replacing it with safer alternatives like sysfs_emit_at, seq_buf, and scnprintf across sysfs and debugfs code paths, plus lpfc's info and symbolic node name reporting. This is…
Rounding out the pull, there's a scattering of real-world bug fixes: a host leak in the snic driver when workqueue allocation fails, a loop timeout bug in qla2xxx, an uninitialized remote-port use in ibmvfc's work handler, and firmware log memory-mapping races fixed in the newer leapraid…
