Linux Kernel: SCSI Layer Gets Context Analysis and a String Function Cleanup
Martin Petersen's final SCSI pull for the 7.3 merge window brings compile-time lock checking to the SCSI core and UFS, alongside a broad cleanup replacing the deprecated string-concatenation function across the LPFC driver, plus assorted driver bug fixes.

It's August 30th, 2026, and this one's about hardening the SCSI stack for the long haul.
The headline change here is the enabling of context analysis for the SCSI core and UFS. In plain terms: the compiler can now check that locking rules around host state are actually followed, rather than trusting developers to get it right by convention. That's paired directly with commits protecting host state…
Second theme: cleanup of the LPFC Fibre Channel driver. Multiple commits strip out the old string-concatenation function in favor of safer alternatives — sysfs emit at, seq buf, and scnprintf, depending on context. Same motivation across every instance: the old function doesn't know the size of its destination…
Beyond those two threads, it's routine hardening: a host leak fix in the snic driver when workqueue allocation fails, an uninitialized variable fix in ibmvfc's worker thread, and timeout and error-code corrections in qla2xxx. The leapraid driver picked up fixes for sysfs attribute handling and for race conditions…
What's next: context analysis is now live for the SCSI core, so new patches touching host locking will need to satisfy the compiler's checks — expect that to surface…
That's…
